A laser in visible is used in Raman spectroscopy and the resultant spectrum is in IR and Microwave region(which means molecular vibrations and rotations are excited), what type of interaction is this that induces these levels? ( I cannot think more than..."To be Raman active molecules should posses anisotropic polarizability".)my question is how vibration or rotation can be excited during the scattering? (As the source used is visible, I think some basic understanding is missing from my side)
