Raman scattering

Raman scattering or the Raman effect (pronounced /ˈrɑːmən/) is the inelastic scattering of a photon. Discovered by Sir Chandrasekhara Venkata Raman in liquids[1] and by Grigory Landsberg and Leonid Mandelstam in crystals

In 1922, Indian physicist C. V. Raman published his work on the "Molecular Diffraction of Light," the first of a series of investigations with his collaborators which ultimately led to his discovery (on 28 February 1928) of the radiation effect which bears his name. The Raman effect was first reported by C. V. Raman and K. S. Krishnan, and independently by Grigory Landsberg and Leonid Mandelstam, in 1928. Raman received theNobel Prize in 1930 for his work on the scattering of light. In 1998 the Raman Effect was designated an ACS National Historical Chemical Landmark in recognition of its significance as a tool for analyzing the composition of liquids, gases, and solids
