Abstract

Raman scattering is due to the inelastic scattering of photons by excitations in molecules, liquids or solids. This chapter deals specifically with the inelastic scattering of photons by lattice vibrations (phonons) in crystals, but the treatment is also applicable to other types of collective excitations in a crystal. The basic notions are introduced in the first section. First-order scattering by phonons is then described. A table summarizes the symmetry properties of Raman tensors in the 32 crystallographic classes. Further sections discuss morphic effects in Raman scattering, spatial-dispersion effects and higher-order scattering.
