Homework Statement
I understand that in the fluorescence, the incident photon is absorbed by the molecule, and the molecule while returning to its original ground level releases lesser energy. Similarly, in Raman effect also a photon is incident on a liquid molecule. In stokes' lines the lesser frequency is emitted and in the Anti stokes' lines the greater frequency is released. My doubt is: Is the photon completey absorbed by the molecule and the exited molecule gives up a lesser or greater energy in the form of photons (as in the case of fluorescence) or the collided photon itself is simply bounced from the liquid molecule and come out with changed frequencies? In that case what about the energies emitted by the excited molecules themselves while returning to the ground level? Where do they go? Do they also accompany the scattered photons? Also what does a "ground electronic state" exactly stand for? Is it for the K- level of a molecule, ie. the level corresponding to the principal quantum number 1?
