Kinematics
Vacher, R. and Courtens, E.  International Tables for Crystallography (2013). Vol. D, Section 2.4.4.1, p. 350 [ doi:10.1107/97809553602060000914 ]
Kinematics 2.4.4.1. Kinematics Brillouin scattering occurs when an incident photon at frequency interacts with the crystal to either produce or absorb an acoustic phonon at , while a scattered photon at is simultaneously emitted. Conservation of energy gives where positive corresponds to the anti-Stokes process. Conservation of momentum can be written ...
