How can someone use Raman Spectroscopy to obtain information for the phonon modes of a crystal? I am asking for some paper that contains information about Raman Spectroscopy and Phonons from an experimental point of view.

The photon momentum of visible light is small compared to phonon momentum in crystals so one can only see phonons at $\Delta k=0$.

But now there is the technique of (Resonant) X-ray Raman Scattering with resolution high enough to see phonons and magnons and measure their dispersion curves.
