Raman occurs in uv, visible and IR, just depends on your source laser. I am not sure what effect you are referring to then.

The whole electromagnetic spectrum is really really large (really infinite) At any rate, both molecular nitrogen N2 and molecular oxygen O2 absorb very strongly in the ultraviolet. Almost 100% of the incident light from the sun below 190 nm is absorbed. Modtran is a wonderful program for...

Raman scattering zhange, The phenomena you are referring to is Raman scattering (discovered it 1928 by C.V. Raman). When light interacts with a molecule an instantaneous (near-instantaneous) effect occurs where the light is absorbed generally to a virtual state (exciting the molecule) then...
