Raman effect

It is the inelastic scattering of a photon by molecules which are excited to higher vibrational or rotational energy levels.  In this phenomenon, some part of light beam after passing through transparent medium gets scattered. This phenomenon of scattering of light is termed as Raman Scattering and the cause of scattering is called the Raman Effect. The wavelength of these scattered rays is different from that of the incident rays of light.
