A laser source is used to
A laser source is used to investigate the vibrational and rotational energy levels of molecules in the type of spectroscopy that utilizes this effect. Resulting radiation higher in frequency than the incident radiation is termed anti-Stokes radiation, while radiation that falls below in terms of frequency is known as Stokes radiation. The scattering that results occurs due to inelastic collisions between molecules and the photons of monochromatic light. FTP, identify this scattering effect discovered in 1928 by its namesake Indian physicist.
