CV Raman
Sir CV Raman ( Chandrasekhara Venkata Raman ; Tamil ச. வெ. இராமன் ; [ ˈrɑːmən ]; born November 7, 1888 in Tiruchirappalli ; † November 21, 1970 in Bangalore ) was an Indian physicist and Nobel Prize winner .
Life
CV Raman was born on November 7, 1888 as the son of a math and physics lecturer in Tiruchirappalli (Trichinopoly) in southern India. He attended the Presidency College in Chennai (Madras) from 1902 , where he received his BA in 1904 and his MA in 1907 . As the conditions for an academic career were unfavorable at the time, he accepted a position at the Indian Ministry of Finance - but found opportunities in his scant free time to continue his experimental research in the laboratory of the Indian Society for the Advancement of Science in Calcutta (Kolkata). In 1917 he was offered the newly created Palit Chair for Physics at the University of Calcutta , which he accepted. In 1933 he moved to the Indian Institute of Science in Bangalore as a professor and after 1948 was director of the Raman Institute for Research, which he set up and supervised himself.
Raman founded the Indian Journal of Physics in 1926 and promoted the establishment of an Indian Academy of Sciences, which he headed as founding president.
Raman died in Bangalore on November 21, 1970. His nephew Subrahmanyan Chandrasekhar was awarded the Nobel Prize in Physics in 1983. S. Pancharatnam and Sivaramakrishna Chandrasekhar , who are also related to him, also worked at his institute for a time .

Raman is best known for the experimental discovery of Raman scattering (inelastic scattering of light , elastic scattering is called Rayleigh scattering ). The method of Raman spectroscopy derived from this is one of the most important investigation methods in molecular and solid-state physics and an important method of material characterization. Further research concerns the modeling of the viscosity of liquids.
