Explanation:
Raman effect deals with inelastic scattering of photon particles by interaction with vibrational and rotational transitions in the bonds( Raman scattering can occur with a change in energy of a molecule due to a transition) it has nothing to do with polarisation, quantum nature, wave nature (photon scattering ) and Brillouin zone scattering.
