సర్ చంద్రశేఖర వెంకట రమణ 1888 వ సంవత్సరంలో ఒక తమిల హిందూ ఫామిలీ లో జన్మించారు. CV రామన్ భారత దేశం యొక్క భౌతిక శాస్త్రవేత్తలతో ప్రసిది చెందిన శాస్త్రవేత్త, రామన్ గారు లైట్ స్కేటరింగ్ (కాంతి వికిరణం) గురించి చేసిన పరిశోధన ప్రపంచం మొత్తానికి ఇండియా గురించి తెలిసేలా చేసింది.

రామన్ గారు చేసిన పరిశోధన నే ఇప్పుడు రామన్ ఎఫెక్ట్ అంటారు. కాంతి ఒక పారదర్శక వస్తువు గుండా ప్రవహించినపుడు కాంతి యొక్క Wavelength మరియు Amplitude మారుతుంది అని రామన్ కనుగొనడం జరిగింది. రామన్ గారు చేసిన కృషి కి గాను 1930లో భౌతికశాస్త్రంలో నోబెల్ బహుమతి కూడా లభించింది.నోబెల్ బహుమతి తీసుకున్న వాళ్లలో భారత దేశం నుంచి మొట్ట మొదటి వ్యక్తి  గా పేర్కొనబడతారు.

బాల్యం : 

రామన్ గారు  చంద్రశేఖర్ రామనాథన్ ఇయర్, పార్వతి అమ్మాల్ అనే  దంపతులకు 1888 వ సంవత్సరంలో 2 వ సంతానంగా జన్మించడం జరిగింది. రామన్ గారు మంచి డబ్బులు సంపాదించే కుటుంబం లో పుట్టారు, రామన్ గారి నాన్న వైజాగ్ కి తరలి వెళ్ళినప్పుడు భౌతిక శాస్త్రాన్నే బోధించేవారు. రామన్ గారు 11  సంవత్సరాలప్పుడు 10 వ తరగతిలో పాసయ్యారు, చిన్నప్పటి నుంచి చదువులో చాలా చురుకుగా ఉండేవారు. 

1904 వ సంవత్సరంలో యూనివర్సిటీ  అఫ్ మద్రాస్ నుంచి తన B.A డిగ్రీ ని పూర్తి  చేసుకున్నారు, ఈ కాలేజీ లో మొదటి స్థానంలో మార్కులు వచ్చినందుకు గాను గోల్డ్  మెడల్ కూడా రావటం జరిగింది. 18 సంవత్సరాలప్పుడు డిఫ్ఫ్రాక్షన్ ఆఫ్ లైట్ (కాంతి యొక్క విక్షేపం) పై మొదటి సైన్స్ పేపర్ ను రాసారు, రెండవ పేపర్ సర్ పేస్ టెన్షన్ ఆఫ్ లిక్విడ్స్ (ద్రవాల ఉపరితల ఉద్రిక్తత) పై రాయటం జరిగింది.

రామన్ తెలివి తేటలను చూసిన తన ప్రొఫెసర్ రిచర్డ్ ఇంగ్లాండ్ వెళ్లి తన పరిశోధన కొనసాగించమని అడిగారు, కానీ రామన్ ఆరోగ్య కారణాల వళ్ళ ఇంగ్లాండ్ ప్రయాణం రద్దు చేసుకున్నారు.  

రామన్ తన చదువు ముగించుకున్న తరవాత ప్రొఫెసర్ గా వివిధ కాలేజీ లలో లెక్చర్స్ తీసుకునేవారు. 1943 వ సంవత్సరంలో TCM లిమిటెడ్ అనే కంపెనీ ను కూడా మొదలుపెట్టారు.  

సైన్స్ లో రామన్ చేసిన కృషి :   

సంగీతంలో ధ్వని కంపనాలు: .

రామన్ గారు సంగీతానికి సంబంధించిన సాధనాలలో కలిగే కంపనలను చదవటం మొదలుపెట్టారు, భారతదేశంలో ఉపయోగించే డ్రమ్స్, తబలా, మ్రిదంగం లాంటి సాధనాల గురించి మరియు అవి పుట్టించే కంపనలను గురించి కూడా చదివారు.      

  సముద్రం యొక్క రంగు :  

CV రామన్ గారు ఇంగ్లాండ్ నుండి ఇండియా తిరిగి వస్తున్నప్పుడు సముద్రం లోని నీటి రంగు నీలి రంగులో ఉండటానికి కారణం కాంతి వికిరణం అని తెలిపారు. 

ఈ ప్రయాణం ఒక నౌక ద్వారా జరిగినందున తన వద్ద ఉన్న కొద్దీ పరికరాలతో ఈ ప్రయోగాలను చేశారు మరియు తన ప్రయాణం పూర్తి అయ్యే ముందు ఒక ఆర్టికల్ “The colour of the sea”  కూడా రాసారు.

రామన్ ఎఫెక్ట్ :         

కాంతి ఒక దుమ్ము లేని పారదర్శక రసాయన సమ్మేళనం గుండా ప్రవహించినప్పుడు ఆ కాంతి వికిరణం చెందుతుంది, ఇలా జరిగినప్పుడు కాంతి యొక్క కొంత భాగం వేరే దిశలో ప్రయాణిస్తుంది. ఇలా వేరే దిశలో ప్రయాణించిన కాంతి యొక్క తరంగ ధైర్యం మారుతుంది, ఇలా వికిరణానికి ముందు తరవాత తరంగ ధైర్యలలో వచ్చే మార్పును రామన్ ఎఫెక్ట్ అని అంటారు. 

వ్యక్తిగత జీవితం :   

రామన్ గారు తనకు 19 సంవత్సరాలు ఉన్నప్పుడు లోకసుందరి అమ్మాళ్ అనే 13  సంవత్సరాల అమ్మాయి తో వివాహం చేసుకున్నారు. ఈ దంపతులకి ఇద్దరు సంతానం ఒకరు చంద్రశేఖర్ రామన్ మరియు రేడియో- ఆస్ట్రోనామెర్ (ఖగోళ శాస్త్రవేత్త) వెంకటరామన్ రాధాకృష్ణన్.     

రామన్ తన జీవిత కాలంలో కాంతి వికిరణం లక్షణాలు కలిగి ఉన్న రాళ్లు, ఖనిజాలు, మరియు ఇతర పదార్థాలను సేకరించేవారు, వీటిలో ఎక్కువగా బహుమతిగా వచ్చేవి.

మరణం : 

రామన్ తన జీవిత కాలంలో దేవుని పట్ల నమ్మకం పెంచుకోలేదు, నాస్తికుని గానే ఉన్నారు, తనకు దేవుని మీద స్వర్గం మరియు నరకం మీద నమ్మకం లేదని మనము పుట్టిన తరవాత మన జీవితాన్ని మంచిగా గడపాలని తెలిపేవారు. రాబోయే కాలంలో సైన్స్ దేవుని గురించి ఇంకా ఎక్కువగా పరిశోధనలను జరిపి చెప్పవచ్చు అని అనేవారు.    

రామన్ గారు 21 నవంబర్ 1970 వ సంవత్సరంలో 82 వయస్సులో గుండె పోటు వళ్ళ మరణించారు. తాను మరణించిన తర్వాత సాధారణంగా దహన సంస్కారాలు చేయాలనీ ఎక్కువగా ఆచారాలు పాటించవద్దు అని తన భార్య కు ముందే చెప్పారు.

C.V. Raman and the Raman Effect

International historic chemical landmark.

Designated December 15, 1998, at the Indian Association for the Cultivation of Science in Jadavpur, Calcutta, India.

Commemorative Booklet (PDF)

"I propose this evening to speak to you on a new kind of radiation or light emission from atoms and molecules." With these prophetic words, Professor C. V. Raman of Calcutta University began his lecture to the South Indian Science Association in Bangalore on March 16, 1928. Raman proceeded to describe a discovery that resulted from a deceptively simple experiment. Conducted far from the great centers of scientific research in the Western world, the results would capture the attention of scientists around the world and bring many accolades, including the Nobel Prize, to their discoverer.

Raman’s Fascination with Light Scattering

Raman measures the effect of light scattering, raman effect as the physicist’s tool.

• Raman Effect as the Chemist’s Tool

The Laser and Raman Spectroscopy

Biography of sir c.v. raman, further reading, landmark designation and acknowledgments, cite this page.

Educated entirely in India, C.V. Raman made his first trip to London in 1921, where his reputation in the study of optics and especially acoustics was already known to the English physicists J. J. Thomson and Lord Rutherford, who gave him a warm reception. Raman's specialty had been the study of the vibrations and sounds of stringed instruments such as the violin, the Indian veena and tambura, and two uniquely Indian percussion instruments, the tabla and the mridangam.

But it was the return trip from London to Bombay aboard the SS Narkunda that would change forever the direction of Raman's future. During the fifteen-day voyage, his restless and probing mind became fascinated with the deep blue color of the Mediterranean. Unable to accept Lord Rayleigh's explanation that the color of the sea was just a reflection of the color of the sky, Raman proceeded to outline his thoughts on the matter while still at sea and sent a letter to the editors of the journal Nature when the ship docked in Bombay.

A short time later Raman was able to show conclusively that the color of the sea was the result of the scattering of sunlight by the water molecules. Ironically, it was exactly the same argument that Rayleigh had invoked when explaining the color of the sky — the blue was the result of the scattering of sunlight by the molecules in the air.

Raman was now obsessed with the phenomenon of light scattering. His group in Calcutta began an extensive series of measurements of light scattered primarily by liquids but also by some solids. As a result, Raman was able to explain the blue color observed in the ice of Alpine glaciers.

Back to top

Analysis of light scattered by a liquid is not an easy task, and much of the early work in Calcutta was done by the visual observation of color rather than precise measurements of the light's wavelength as shown in Figure 1 at right. The fundamentals of Raman's crucial experiment are outlined in Figure 2.

The violet light of the solar spectrum is isolated with a violet filter and passed through the liquid sample. Most of the light emerging from the liquid sample is the same color as the incident violet beam: the so-called Rayleigh scattered light. However, Raman and K. S. Krishnan were able to show that some of the scattered light was a different color, which they could isolate by using a green filter placed between the observer and the sample. The advantage of using a visual observation is that several substances can be studied quickly. In his first report to Nature , titled "A New Type of Secondary Radiation," Raman indicated that approximately 60 different liquids had been studied, and all showed the same result — some scattered light had a different color than the incident light. "It is thus," Raman said, "a phenomenon whose universal nature has to be recognized."

The Raman Effect is a very weak effect; only one in a million of the scattered light particles, or photons, actually exhibits the change in wavelength. This explains, in part, why the effect was not discovered earlier. In all of the early light-scattering studies, the excitation source was sunlight, which Raman has described as being plentiful in Calcutta, but it still lacked the desired intensity. The acquisition in 1927 by the IACS of a seven-inch (18 cm) refracting telescope enabled Raman to condense the sunlight and create a more powerful light source for his studies. By early 1928, mercury arc lamps were commercially available, and he switched to this even more intense light source.

Raman knew that visual and qualitative observations alone would not be sufficient information. He methodically set out to measure the exact wavelengths of the incident and Raman scattering by replacing the observer with a pocket spectroscope. He ultimately replaced it with a quartz spectrograph with which he could photograph the spectrum of the scattered light and measure its wavelength. These quantitative results were first published in the Indian Journal of Physics on March 31, 1928.

The significance of the Raman Effect was recognized quickly by other scientists. Professor R. W. Wood of Johns Hopkins cabled Nature to report that he had verified Raman's "brilliant and surprising discovery ... in every particular. It appears to me that this very beautiful discovery which resulted from Raman's long and patient study of the phenomenon of light scattering is one of the most convincing proofs of the quantum theory."

Raman had also recognized that his discovery was important to the debate in physics over the new quantum theory, because an explanation of the new radiation required the use of photons and their change in energy as they interacted with the atoms in a particular molecule. Raman also knew that there was a more important result, remarking in his 1930 Nobel Prize address that "... the character of the scattered radiations enables us to obtain an insight into the ultimate structure of the scattering substance."

In the first seven years after its discovery, the Raman Effect was the subject of more than 700 papers in the scientific literature, mostly by physicists who were using the technique to study the vibration and rotation of molecules and relating those phenomena to the molecular structure. Then, as noted by Raman biographer G. Venkataraman, there was a decline in interest, as "the first bloom of novelty had worn off and physicists were satisfied that they understood the origin of the effect." At the same time, chemists became interested in the Raman Effect as an analytical tool. In James Hibben's words, "The Raman Effect became the adopted child of chemistry."

Raman Effect as a Chemist’s Tool

By the late 1930s the Raman Effect had become the principal method of nondestructive chemical analysis for both organic and inorganic compounds. The unique spectrum of Raman scattered light for any particular substance served as a "fingerprint" that could be used for qualitative analysis, even in a mixture of materials. Further, the intensity of the spectral lines was related to the amount of the substance. Raman spectroscopy could be applied not only to liquids but also to gases and solids. And unlike many other analytical methods, it could be applied easily to the analysis of aqueous solutions. It was a ubiquitous technique, giving information on what and how much was present in a plethora of samples.

The use of Raman spectroscopy as a basic analytical tool changed sharply after World War II. During the war, infrared spectroscopy was enhanced by the development of sensitive detectors and advances in electronics. Infrared measurements quickly became routine operations, while Raman measurements still required skilled operators and darkroom facilities.

Raman spectroscopy could no longer compete with infrared until another development in physics — the laser — revived Raman spectroscopy in a new form beginning in the 1960s.

Raman understood the need for more intense light sources to amplify the effect and observation of the scattered light. The laser provided an even more intense source of light that not only could serve as a probe exploring the properties of the molecule but could also induce dramatically new effects.

With the development of the Fourier transform (FT) technique and the application of computers for data handling, commercial FT-Raman spectrometers became available in the late 1980s, resulting in resurgence in the use of the original Raman Effect.

The new Raman spectroscopy has been used to monitor manufacturing processes in the petrochemical and pharmaceutical industries. Illegal drugs captured at a crime scene can be analyzed rapidly without breaking the evidence seal on the plastic bag. Chemists can watch paint dry and understand what reactions are occurring as the paint hardens. Using a fiber-optic probe, they can analyze nuclear waste material from a safe distance. Photochemists and photobiologists are using laser Raman techniques to record the spectra of transient chemical species with lifetimes as small as 10 -11 seconds. Surface-enhanced Raman spectroscopy is used for studying surfaces and reactions on surfaces. And, according to Kathy Kincade, Raman spectroscopy "has the ability to provide specific biochemical information that may foreshadow the onset of cancer and other life-threatening illnesses."

In his 1928 talk in Bangalore, Raman concluded, "We are obviously only at the fringe of a fascinating new region of experimental research which promises to throw light on diverse problems relating to radiation and wave theory, X-ray optics, atomic and molecular spectra, fluorescence and scattering, thermodynamics, and chemistry. It all remains to be worked out."

Seventy years later scientists are still actively working out the results and practical applications of Raman's deceptively simple experiment.

According to Hindu tradition, Raman was originally named Venkataraman after a Hindu deity, preceded by the initial of his father's first name, Chandrasekhara. In school his name was split to C. Venkata Raman, which later became C.V. Raman. With a father who was a professor of physics and mathematics and a mother who came from a family of Sanskrit scholars, Raman exhibited a precocious nature at an early age. He received a B.A. degree from Presidency College in Madras at the age of 16, placing first in his class and receiving a gold medal in physics.

While studying for his M.A. degree, he published his first research paper in Philosophical Magazine at the age of 18. It was the first research paper ever published from Presidency College.

Because of poor health, he was unable to go to England for further education. With nothing else available in India, in 1907 he passed the Financial Civil Service exam, married, and was posted to Calcutta as assistant accountant general.

Shortly after arriving in Calcutta, Raman began after-hours research at the Indian Association for the Cultivation of Science (IACS). In the first 10 years, working almost alone, he published 27 research papers and led the way for the IACS to become recognized as a vibrant research institute. Much of this early work was on the theory of vibrations as it related to musical instruments. After brief postings in Rangoon and Nagpur, he returned to Calcutta, took up residence next door to the IACS, and constructed a door that led directly into the institute, giving him access at any time. He received research prizes in 1912 and 1913 while he was still a full-time civil servant. He also increased the IACS reputation with his extensive lectures in popular science, holding the audience spellbound with his booming voice, lively demonstrations, superb diction and rich humor.

At the age of 29 he resigned from his lucrative civil service job when Sir Ashutosh Mukherjee, vice-chancellor, Calcutta University, offered him the Palit Chair Professorship. He continued to lecture even though it was not required, and he used the IACS as the research arm of the university. By the time of his first visit to England in 1921, his reputation in physics was well known. Three years later he was elected a Fellow of the Royal Society — only the fourth Indian so honored. That same year he toured the United States, spending four months at the California Institute of Technology through the invitation of Nobel Laureate Robert Millikan.

After discovering the Raman Effect in 1928, he was knighted by the British government in India and received the Nobel Prize in physics in 1930. Three years later, Raman left Calcutta for Bangalore, where he served as head of the Indian Institute of Science. There he continued his work on the Raman Effect and became interested in the structure of crystals, especially diamond. In 1934 he founded the Indian Academy of Science and began the publication of its Proceedings .

In 1948 he became director of the newly constructed Raman Research Institute, where he remained continually active, delivering his last lecture just two weeks before his death. His research interests changed in later years when he primarily investigated the perception of color.

Jagdish Mehra, a biographer, states, "Educated entirely in India, Raman did outstanding work at a time when the small Indian community worked almost entirely in isolation and few made science a career. In fostering Indian science, Raman emerged as one of the heroes of the Indian political and cultural renaissance, along with ... Mahatma Gandhi and Jawaharlal Nehru." But as Raman himself once said, outstanding investigators "are claimed as nationals by one or another of many different countries. Yet in the truest sense they belong to the whole world."

Landmark Designation

The American Chemical Society and the Indian Association for the Cultivation of Science dedicated The Raman Effect an International Historic Chemical Landmark on December 15, 1998 at the Indian Association for the Cultivation of Science in Jadavpur, Calcutta, India. The plaque commemorating the event reads:

At this institute, Sir C. V. Raman discovered in 1928 that when a beam of coloured light entered a liquid, a fraction of the light scattered by that liquid was of a different color. Raman showed that the nature of this scattered light was dependent on the type of sample present. Other scientists quickly understood the significance of this phenomenon as an analytical and research tool and called it the Raman Effect. This method became even more valuable with the advent of modern computers and lasers. Its current uses range from the non-destructive identification of minerals to the early detection of life-threatening diseases. For his discovery Raman was awarded the Nobel Prize in physics in 1930.

Sir CV Raman: 135th Birth Anniversary – A Pioneer of Indian Science

Context: The 135th birth anniversary of great Indian Physicist Sir CV Raman will be celebrated on 7th November 2023.

From Finance to Physics: The Journey of Sir CV Raman

• Birth: Chandrasekhar Venkata Raman was born in Tiruchirappalli, Madras Presidency on 7 November, 1888. 

• He obtained his Masters degree with the highest distinction  from University of Madras.
• However, he continued doing research at IACS (Indian Association for the Cultivation of Science).
• Career Shift : He resigned from his government job in 1917 and accepted the offer of Palit Chair of Physics at Calcutta University .
• Appointment in IISc: He was appointed as the Director of the Indian Institute of Science (IISc) in Bangalore in 1933. He served at the IISc till his retirement in 1948.

Sir CV Raman: Pioneering Contributions to Physics and Scientific Inquiry

• Initial Research: He started research early in his student life. His first research paper, called “ Unsymmetrical diffraction bands due to a rectangular aperture “, was published in 1906 while he was still a graduate student. 

• This unknown type of scattering of light, was named “ modified scattering ” was subsequently termed the Raman Effect or  Raman scattering .
• He conducted studies of the acoustics of various violin and related instruments , including Indian stringed instruments. He performed experiments with mechanically performed violins.
• His studies on the harmonic nature of the sounds of tabla and mridangam were the first such experiments on Indian percussions.
• During his visit to England, he studied how sound travels in the  Whispering Gallery  of the dome of St Paul’s Cathedral in London.
• Later, he conducted a full-fledged study on the sea water of Bay of Bengal to come to the conclusion that visible color of water is mainly attributed to the selective absorption of longer wavelengths of light in the red and orange regions of the spectrum, owing to overtones of the infrared  absorbing O-H (oxygen and hydrogen combined) stretching modes of water molecules. 
• Apart from studying composition and characteristics of the diamonds , he also studied various colourful materials, such as labradorite, agate, opal, and pearls .  
• Angular Momentum: Along with his student, He discovered that light photons had angular momentum or spin . This angular momentum of EMR is shifted to the atoms that absorb it.

Raman completed his master’s in physics from the University of Madras in 1907 . Afterward, he took a job as an accountant with the Indian government but later became a physics professor at the University of Calcutta in 1917 .

While studying light’s behavior in different materials in 1928, he noticed a unique light scattering pattern. This discovery, known as the Raman frequencies, relates to energy changes in the substance the light passes through.

In 1929, Sir C.V. Raman was given the title of ‘knight’ . In 1933, he joined the Indian Institute of Science in Bangalore as the physics department head. By 1947, he led the Raman Research Institute. In 1961, he became part of the Pontifical Academy of Science.

He helped establish many Indian research centers, started the Indian Journal of Physics and the Indian Academy of Sciences, and trained many students. These students got significant roles in Indian and Myanmar universities and government. His nephew, Subrahmanyan Chandrasekhar, won the 1983 Nobel Prize for Physics alongside William Fowler.

C.V. Raman College

Sir C.V. Raman’s educational journey was marked by his time at the Presidency College in Madras (now Chennai) where he pursued his undergraduate and postgraduate studies in Physics.

What is C.V. Raman Effect?

The Raman effect describes how light changes its wavelength after interacting with molecules. When light passes through a clear, dust-free chemical sample, a tiny portion reflects in different directions from the original beam. Most reflected light has the same wavelength, but some don’t due to the Raman effect.

This phenomenon was named after Indian physicist Sir Chandrasekhara Venkata Raman, who reported it in 1928. Though the effect was described theoretically by Austrian physicist Adolf Smekal in 1923 and noticed by Russian physicists Leonid Mandelstam and Grigory Landsberg just a week before Raman, it’s Raman who gets the credit.

If we think of incoming light as made of particles or photons, these particles hit the sample’s molecules. Most times, they bounce back without changing. But sometimes, the molecules either take or give energy to these photons. This changes the photon’s energy, and hence its frequency. The change in frequency helps understand the energy shifts during this interaction.

However, the Raman effect is weak. In liquids, the changed light’s strength might be only a tiny fraction of the original beam. Still, the Raman pattern is unique for different molecules and shows how many molecules are involved. That’s why it’s useful in analyzing materials.

The energy changes in the Raman effect come from the molecule’s rotational and vibrational movements. It’s challenging to see just rotational changes, especially in liquids. Most studies focus on vibrational changes which are clearer and can be seen in gases, liquids, and solids. Among these, liquids and solids are studied more since gases show a very faint Raman effect.

C.V. Raman Contribution to Science

Sir C.V. Raman made good use of his time with Professor Jones during his physics studies at Presidency College. They had limited lab tools, but Raman used them to explore countless questions. Often, these questions had no answers in books, so Raman’s nature pushed him to do experiments.

He explored how light spreads even though he knew its wave nature. He showed his findings to Professor Jones, who took a long time to respond. Raman knew of a magazine, the Philosophical Magazine, maybe from a nearby library. In 1906, when he was only 18, he wrote a paper for it.

This was notable because his college wasn’t known for research. Soon after, R.W. Wood from Johns Hopkins University published a related paper and later announced Raman’s discovery of the Raman Effect.

In 1917, Raman moved to teach physics at the University of Calcutta and also worked at the IACS, climbing to a top position. He called this time his “golden age” and was surrounded by talented students. In 1929, he led an important science meeting.

C.V. Raman also studied the science behind musical instruments. He came up with ideas explaining how string instruments work, which was better than previous theories. He was the first to study sounds from Indian drums. In 1933, Raman became the director of the Indian Institute of Science in Bangalore.

Before him, most leaders and teachers there were British. He continued to teach physics for two more years. In 1947, when India became independent, he became its first National Professor. In 1948, he left the institute and in 1949 started the Raman Research in Bangalore, where he worked until he passed away in 1970.

C.V. Raman Achievements and Awards

Sir C.V. Raman received many honorary doctorates and was part of numerous science societies worldwide. He was part of societies in Munich, Zürich, Glasgow, Ireland, Hungary, the Soviet Union, America, Romania, and Czechoslovakia. In 1924, he became a Fellow of the Royal Society, but left in 1968, a unique case for an Indian. He led the 16th Indian Science Congress in 1929 and was the first leader of the Indian Academy of Sciences from 1933 until he passed away. In 1961, he joined the Pontifical Academy of Sciences.

Sir C.V. Raman worked for the Indian Finance Service and earned several awards. In 1912, he got the Curzon Research Award, and in 1913, the Woodburn Research Medal. In 1928, the Accademia Nazionale delle Scienze in Rome gave him the Matteucci Medal. He became a knight in 1930 and the Viceroy of India, Lord Irwin, honored him at the Viceroy’s House in New Delhi. He won the Nobel Prize in Physics in 1930 for his work on light scattering.

This made him the first Asian to win a Nobel Prize in Science. Rabindranath Tagore, another Indian, had won a Nobel Prize for Literature in 1913. Raman also received the Hughes Medal in 1930, the Franklin Medal in 1941, the Bharat Ratna award in 1954 (shared with C. Rajagopalachari and Sir Sarvepalli Radhakrishnan), and the Lenin Peace Prize in 1957.

Mains: Achievements of Indians in science and technology; indigenization of technology and developing new technology.

Sir CV Raman was born in Tiruchirappalli, Tamil Nadu, on November 7, 1888. Chandrasekhara Venkata Raman, the son of a teacher who taught physics and mathematics, was raised in an academic environment from an early age. After earning his M.A. in physics in 1907 from Presidency College, Madras, Sir CV Raman was involved in research in the area of atomic physics and optics. The first Asian to get the Nobel Prize in Physics and the first Bharat Ratna awardee, Sir CV Raman is best known for his advanced theory of the scattering of light - an inelastic theory of scattering .

Sir CV Raman and his student KS Krishnan found that the light, after passing through a transparent medium, changes its wavelength and energy during the scattering - the phenomenon is called the Raman Effect or Raman Scattering , which has various applications in spectroscopy.

Sir CV Raman and Raman Effect

Rayleigh had already established the phenomenon of the scattering of light and had provided reasons for the blue colour of the sky. But his work was based on the multi-wavelength light passing through the atmospheric gases that scatter the light of lower wavelengths. C. V. Raman established a more advanced theory of scattering.

Molecular Scattering of Light

When light is scattered by a molecule, the oscillating electromagnetic field of a photon induces a polarisation of the molecular electron cloud, which leaves the molecule in a higher energy state after the energy of the photon is transferred to the molecule.

• This is sometimes referred to as the virtual state of the molecule and can be thought of as the formation of a very brief-lived complex between the photon and molecule.
• The virtual state is unstable and the photon is reemitted almost immediately, as scattered light.
• The wavelength of the scattered photon is equal to that of the incident photon in the vast majority of scattering events because the energy of the molecule remains constant following its interaction with the photon. This is the main process and is known as elastic (energy of a scattering particle is conserved) or Rayleigh scattering .
• Sir CV Raman and his student, K. S. Krishnan, in 1928 found an inelastic scattering of photons by matter (medium), meaning that there is both an exchange of energy and a shift in the light's wavelength. This phenomenon is called the Raman Effect .
• They found that there is a shift in the energy of the scattered photons (light particles) - either energy absorption (called Stokes scattering ), resulting in a redshift, or energy release (called a nti-Stokes scattering ), resulting in a blue shift.

Importance of the Raman Effect

Although termed a very weak effect, as only one scattered particle out of a million undergoes the shift in wavelength, the Raman Effect has proved to be a significant achievement in physics due to its various applications.

• Nature of light: The Raman Effect further cemented the particle theory of light, which holds that light is composed of tiny particles known as photons.
• Proof of quantum theory: The study of the phenomenon of light scattering is one of the most convincing proofs of quantum theory.
• Applications: The Raman Effect (scattering) provides information on vibrational, rotational and low-frequency modes of energy of molecules, which are the basis of its numerous applications.

Raman Spectroscopy

Raman spectroscopy is an analytical technique where scattered light is used to measure the vibrational energy modes of a sample.

• Raman spectroscopy provides chemical as well as structural information of molecules.
• Raman spectroscopy extracts this information through the detection of Raman scattering from the sample.
• Both organic and inorganic compounds can be nondestructively analysed by the Raman spectroscopy. 
• Resonance Raman Spectroscopy (RRS)
• Surface-enhanced Raman Spectroscopy (SERS)
• Micro-Raman Spectroscopy
• Non-linear Raman Spectroscopic Techniques

Other Scientific Works of Sir CV Raman

Apart from scattering of light, Sir CV Raman was associated with other scientific works. 

• Spin of photons: With Suri Bhagavantam, Sir CV Raman determined the spin of photons in 1932, which further confirmed the quantum nature of light. 
• This effect has enabled optical communication components based on laser systems through the use of modulators and switching systems.
• Study on diffraction of light: He conducted theoretical and experimental studies on the effects of X-rays on infrared vibrations in crystals exposed to ordinary light, as well as on the diffraction of light by hypersonic and ultrasonic acoustic waves.
• From 1944 to 1968, he studied the structure and characteristics of diamonds .
• In the early 1950s, he studied the structure and optical behaviour of many iridescent materials, including labradorite, feldspar, agate, quartz, opal, and pearl. 
• His last interests in the 1960s were in biological properties such as the colours of flowers and the physiology of human vision.

Honours Received by Sir CV Raman

Sir CV Raman has been honoured with a number of awards and recognitions for his contributions.

• In 1930, Sir CV Raman was conferred with the Nobel Prize in Physics. He was the first Asian to get this recognition.
• He was one of the recipients who got the Bharat Ratna for the first time in 1954 (along with S. Radhakrishnan and C. Rajagopalachari).
• Sir CV Raman was awarded the Lenin Peace Prize in 1957.
• Raman, a lunar crater, is named after Sir CV Raman.

National Science Day (NSD)

The day on which the Raman Effect was discovered by CV Raman (February 28, 1928) is commemorated as National Science Day in India.

• History: The National Council for Science and Technology Communication (NCSTC) requested that the Indian government declare February 28 as National Science Day in 1986.
• The then-Indian government agreed and announced the day as National Science Day in 1986.
• February 28, 1987, marked the first National Science Day.
• NSD 2023: "Global Science for Global Wellbeing" is NSD-2023's theme.
• The theme "Global Science for Global Wellbeing" was chosen to increase public understanding of the scientific issues in a global context that are affecting global well-being.

Who is Chandrasekhara Venkata Raman (C. V. Raman)?

Meet Sir CV Raman, Sir Chandrasekhara Venkata Raman born on 7th November 1888 was a brilliant scientist who loved studying light and its behavior. He was so good at it that he won a big prize called the Nobel Prize, becoming the first Indian to do so in his field!

About Sir Raman, He came from a family that really valued education, and he did very well in school. After finishing his studies, he got a job in the finance department because India didn't have many places for scientific research back then. 

But he didn't stop exploring and learning. In his free time, he did exciting experiments and research at the Indian Association of Cultivation of Science in Kolkata, a place for curious minds like his!"

Sir CV Raman's love for science and curiosity about light led to a fantastic discovery. He showed the world that when light travels through a clear material, it can change in a special way. This discovery was so remarkable that he received the Nobel Prize for it, making him a famous scientist not just in India but all around the world.

But let's go back a bit. Sir CV Raman's family believed in the power of education. This belief was like a guiding star in his life. He did exceptionally well in school, and his hunger for knowledge knew no bounds.

Sir CV Raman's journey reminds us that with dedication and curiosity, we can make incredible breakthroughs in the world of science. He's an inspiration for all of us to keep asking questions, exploring, and never giving up on our dreams."

What were C.V. Raman’s experiments?

Sir CV Raman was known for his groundbreaking experiments in the field of optics and light. One of his most famous experiments, for which he received the Nobel Prize in Physics , involved shining light through different materials and observing how it changed. 

He discovered that when light passes through a transparent medium, some of it scatters and changes color. This phenomenon is now called the " Raman Effect ."

In this experiment, he used monochromatic light, which means light of a single color, and observed how it interacted with various substances. By carefully studying the changes in the light's color and properties after passing through the material, he could determine valuable information about the substance's composition and structure. This breakthrough had significant implications for the study of molecular and atomic physics.

Apart from the Raman Effect, Sir CV Raman conducted various experiments related to the properties of light, like polarization, diffraction, and interference. His work in these areas contributed to our understanding of how light behaves and interacts with matter.
