Sir C. V. Raman receives the Nobel Prize in Physics "for his work on the scattering of light and for the discovery of the effect named after him." The Raman Effect is considered very significant in analysing the molecular structure of chemical compounds.
Sir C. V. Raman becomes Honorary Secretary of the Indian Association for the Cultivation of Science at Calcutta.
Sir C. V. Raman is the Director of the Raman Institute of Research at Bangalore, established and endowed by himself. In his studies Raman approaches in a new manner fundamental problems of crystal dynamics. His laboratory deals with the structure and properties of diamond, the structure and optical behaviour of numerous iridescent substances (labradorite, pearly feldspar, agate, opal, and pearls).
Sir C. V. Raman becomes Professor at the Indian Institute of Science at Bangalore. Here Raman pursues his experimental and theoretical studies on the diffraction of light by acoustic waves of ultrasonic and hypersonic frequencies (published 1934-1942), and those on the effects produced by X-rays on infrared vibrations in crystals exposed to ordinary light. In 1934, Raman sponsors the establishment of the Indian Academy of Sciences and serves as President since its inception.
Sir C. V. Raman continues his own private research at the laboratory of the Indian Association for Cultivation of Sciences. The prominence of his work is recognized by his appointment in 1917 to the first endowed chair in Physics at Calcutta University.
Sir C. V. Raman enters Presidency College in Madras. Here he earns his B.A. and wins a gold medal in Physics.
After a successful Civil Service competitive examination, Sir C. V. Raman becomes Deputy Accountant General in Calcutta. Here he works as an auditor for ten years.
Sir C. V. Raman discovers that when a transparent substance is illuminated by a beam of light of one frequency, a small portion of the light emerges at right angles to the original direction, and some of this light is of different frequencies than that of the incident light. These so-called Raman frequencies are equal to the infrared frequencies for the scattering material and are caused by the exchange of energy between the light and the material.
Sir C. V. Raman dies in Bangalore.
Sir C. V. Raman is born in Thiruvanaikaval, Trichinopoly, present-day Tiruchirapalli, Madras Presidency, in British India, to Parvati Ammal (Saptarshi Parvati) and R. Chandrasekhara Iyer, as second of eight children. His father is a lecturer in mathematics and physics, which contributes to introduce Raman in an academic atmosphere.
Raman travels to Europe, destination Oxford. During the trip, he notices the blue colour of the glaciers and the Mediterranean. After some experiments he publishes a note in Nature entitled The Colour of the Sea. He shows that, contrary to Rayleigh's idea that sea reflects the sky colour, the blue colour of sea is instead due to molecular diffraction. This finding opens a new field of research in Calcutta. Further works on the scattering of light leads to the discovery of the Raman Effect in 1928.
Sir C. V. Raman moves to the city of Visakhapatnam where he enters St. Aloysius Anglo-Indian High School. Although he reveals brilliant talent, he is unable to pursue his education overseas because of ill health.
Sir C. V. Raman resigns from his government service. He is appointed the first Palit Professor of Physics at the University of Calcutta. In 1926 he founds the Indian Journal of Physics, of which he is the Editor.
Sir C. V. Raman gains his M.A. degree at Residency College in Madras obtaining the highest distinctions. By the time he completes his master's degree in physics, he has already done original work in optics and acoustics.
