Raman scattering


Raman scattering or the Raman effect /ˈrɑːmən/ is the inelastic scattering of a photon. It was discovered by C. V. Raman and K. S. Krishnan (who was one of C.V. Raman's students) in liquids, and independently by Grigory Landsberg and Leonid Mandelstam in crystals. The effect had been predicted theoretically by Adolf Smekal in 1923.
