Question

what is Raman effect​

Answer 1

Raman scattering or the Raman effect is the inelastic scattering of photons by matter, meaning that there is an exchange of energy and a change in the light's direction. Typically this involves vibrational energy being gained by a molecule as incident photons from a visible laser are shifted to lower energy.

Answer 2

Raman Effect: Change in the wavelength of light that occurs when a light beam is deflected by molecules.
