Sir Chandrasekhara Venkata Raman

Raman, Sir Chandrasekhara Venkata (1888–1970), Indian physicist awarded the 1930 Nobel Prize in physics for his discovery of the Raman effect: When molecules are exposed to a beam of infrared radiation, light scattered by the molecules contains frequencies that differ from that of the beam by amounts characteristic of the molecules. This is the basis for Raman spectroscopy.
