When a monochromatic light beam is incident on a transparent system, most of the light is transmitted; however, a very small portion of the incident light is scattered, and the wavelength of some of this scattered is at a wavelength different than the incident light due to inelastic collisions.
When a monochromatic light beam is incident on a transparent system, most of the light is transmitted; however, a very small portion of the incident light is scattered, and the wavelength of some of this scattered is at a wavelength different than the incident light due to inelastic collisions. Hence, this scattering can serve as a spectroscopic probe of molecular properties, especially the vibrational energy levels.  FTP, identify the scientist who, along with K.S. Krishnan, reported this phenomenon, now named after him.
