Raman Effect

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