Answer 1

The effective specific to the molecules which cause it and it is invented by CV Raman Chandrasekhara Venkata Raman

Answer 2

after discovering the Raman effect in 1928 he was knighted by the British government in India and received the Nobel Prize in physics in 1933 years later Raman left Calcutta for Bangalore where is served as Head of the Indian Institute of Science
Raman effect change in the wavelength of light that occurs when a light beam is deflected by molecules the phenomenon is named for Indian physicist Sir Chandrasekhara Venkata Raman who first published observations on the effect in 1928 describe the effect in 1923
The spectrum of the Raman scattered light depends on the molecular constituents present and their state allowing The spectrum to be used for material identification and analysis Raman spectroscopy is used to analyse a wide range of materials including gases liquids and solids
