TIME REVERSAL SYMMETRY AND THE RAMAN SCATTERING BY CRYSTALS
A.K. Ramdas et S. RodriguezDepartment of Physics, Purdue University, West Lafayette, Indiana 47907, U.S.A.
Abstract
A survey of the effect of time reversal symmetry on the phonon spectra of crystals is presented. The linear wave vector dependence of the dispersion curves of the zone center polar modes as well as splitting of shear acoustic modes are accessible to observation in the Raman and Brillouin spectra of selected lines in suitable crystals.
