Autobiography of dr cv raman

His mind was like the diamond, which he studied and explained. His life's work consisted in throwing light upon the nature of lights, and the world honoured him in many ways for the new knowledge which he won for science. They published their findings in July issue of Naturwissenschaften[ ] and presented their findings at the Sixth Congress of the Russian Association of Physicists held at Saratov between 5 and 16 August.

According to the Nobel Committee, however: 1 the Russians did not come to an independent interpretation of their discovery as they cited Raman's article; 2 they observed the effect only in crystals, whereas Raman and Krishnan observed it in solids, liquids and gases, and therefore proved the universal nature of the effect; 3 the problems concerning the intensity of Raman and infrared lines in the spectra had been explained during the previous year; 4 the Raman method had been applied with great success in different fields of molecular physics; and 5 the Raman effect had effectively helped to check the symmetry properties of molecules, and thus the problems concerning nuclear spin in atomic physics.

Krishnan was not nominated for the Nobel Prize even though he was the main researcher in discovering the Raman effect. He alone wrote all the follow-up studies. By then Raman had developed a different theory and claimed that Born's theory contradicted the experimental data.

In this dispute, Born received support from most physicists, [ ] as his view was proven to be a better explanation. Born later said that Raman probably thought of him as an "enemy. As the editor of Current Science he rejected articles that supported Born's theory. The account was written as a "belated Nobel Prize. In one instance he smashed the bust of Nehru on the floor.

In another, he shattered his Bharat Ratna medallion to pieces with a hammer, as it was given to him by the Nehru government. There they displayed a piece of gold and copper against an ultraviolet light. Nehru was tricked into believing that copper which glowed more brilliantly than any autobiography of dr cv raman metal was gold.

Raman was quick to remark, "Mr Prime Minister, everything that glitters is not gold. On the same occasion Nehru, offered Raman financial assistance to his institute which Raman flatly refused by replying, "I certainly don't want this to become another government laboratory. BhabhaS. Bhatnagarand his once favourite student, Krishnan.

He even called such programmes as the "Nehru—Bhatnagar effect. The Government of Madras advised him to apply for funds from the central government. But Raman clearly foresaw as he replied to C. Subramaniamthen the Minister for Finance Education in Madras, that his proposal to Nehru's government "would be met with a refusal. Raman described AICC authorities as "a big tamasha " drama or spectacle that just kept on discussing issues without action.

As to problems of food resources in India, his advice to the government was, "We must stop breeding like pigs and the matter will solve itself. The Indian Academy of Sciences was born out of conflicts during the procedures of the proposal for a national scientific organization in line with the Royal Society. Raman thought that it should be an exclusively Indian membership as opposed to the general consensus that British members should be included.

He resolved "How can India Science prosper under the tutelage of an academy which has its own council of 30, 15 of who are Britishers of whom only two or three are fit enough to be its Fellows. The Government of India did not recognize it as an official national scientific body, as such the ICSA created a separate organization named the National Institute of Sciences of India on 7 January but again changed to the Indian National Science Academy in He was accused of biased development in physics while ignoring other fields.

Ramaseshanhis nephew and later Director of IISc, reminisced, saying, "Raman went in there like a bull in a china shop. Raman had every intention of giving the full position of professor to Born. The committee, chaired by James IrvinePrincipal and Vice-Chancellor of the University of St Andrewsreported in March that Raman had misused the funds and entirely shifted the "centre of gravity" towards research in physics, and also that the proposal of Born as Professor of Mathematical Physics which was already approved by the Council in November was not financially feasible.

Raman was inclined to take up the second choice. Raman never seemed to have thought highly of the Fellowship of the Royal Society. However, the exact reason was not documented. Particularly after the Independence of Indiathe Royal Society had its own disputes on this matter. Raman wrote to and demanded an explanation from Patrick Blackettthe then President of the society.

He was dejected by Blackett's response that the society had no role in the newspaper. It could have been these cumulative factors as Raman wrote in his resignation letter, and said, "I have taken this decision after careful consideration of all the circumstances of the case. I would request that my resignation be accepted and my name removed from the list of the Fellows of the Society.

Raman was honored with many honorary doctorates and memberships of scientific societies. Inhe was elected a Fellow of the Royal Society. He was the President of the 16th session of the Indian Science Congress in He was the founder and President of the Indian Academy of Sciences from until his death. At this institute, Sir C. Raman discovered in 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.

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.

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.

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 scatteringresulting in a redshift, or energy release called a nti-Stokes scatteringresulting 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.

Raman was born into a south Indian Brahmin family, the s on of R. Chandrasekhara Aiyer and Parvathi Ammal. His exceptional academic prowess shone through as he passed his matriculation at the age of 11 and completed his 12 th class on a scholarship by the age of Inhe joined Presidency College and remarkably, was the only student to receive a first division.

Inhe married Lokasundari Ammal, with whom he had two sons, Chandrasekhara and Radhakrishnan. Although C. Raman initially pursued a career in financial civil services, his unwavering passion for science led him to spend his spare time in a laboratory at the Indian Association for Cultivation of Sciences in Calcutta now Kolkata. Juggling a demanding job with his research endeavors, he worked tirelessly to further his scientific interests, even conducting experiments late into the night.

Inhe joined the University of Calcutta as the first Palit Professor of Physicsmarking the beginning of a distinguished career in academia. Inhe assumed the role of Director at the Raman Institute of Science in Bangalore from to Inhe assumed the role of Director at the Raman Institute of Researchwhich he had established and endowed himself.

He established the Indian Journal of Physics inserving as its editor.
