Question

what is Raman effect
​

Answer 1

Answer:

Classical concept of Raman scattering: When a beam of light interacts with a material, part of it is transmitted, part it is reflected, and part of it is scattered. Over 99% of the scattered radiation has the same frequency as the incident beam: Mie and Rayleigh scattering. A small portion of the scattered radiation has frequencies different from that of the incident beam: Raman and Brillouin scattering, forms of inelastic scattering. The frequency differences between the incident and inelastically scattered radiation are determined by the properties of the molecules of which the material under study is made.

Answer 2

Inelastic scattering of photons by matter
