Observed independently in crystals by Landsberg and Mandelstam, this effect shares its name with one concerning the vibrational and electronic levels of molecules.
The development of the first atomic clock made use of this effect and the ammonia molecule. Observed independently in crystals by Landsberg and Mandelstam, this effect shares its name with one concerning the vibrational and electronic levels of molecules. As a result of it, the scattered photon can have greater energy if the molecule is initially in an excited vibrational state, or it can have less energy than the incident photon. Coming in Stokes and anti-Stokes varieties, for 10 points, name this type of inelastic scattering named for an Indian scientist.
