Abstract
A review is given of progress in the theoretical and experimental study of the Raman effect in crystals during the past ten years. Attention is given to the theory of those properties of long-wavelength lattice vibrations in both cubic and uniaxial crystals which can be studied by Raman scattering. In particular the phenomena observed in the Raman scattering from crystals which lack a centre of inversion are related to the theory. The angular variations of the scattering by any type of lattice vibration in a crystal having any symmetry can be easily calculated using a complete tabulation of the Raman tensor. Recent measurements of first-order lattice vibration spectra are listed. A discussion of Brillouin scattering is included. The relation of second-order Raman spectra to critical points in the lattice vibration density of states is discussed, and measurements of the second-order spectra of diamond and the alkali halides are reviewed. The theory and experimental results for Raman scattering by electroni...

Infrared Lattice Absorption in Ionic and Homopolar Crystals

TL;DR: In this article, a qualitative understanding of the contribution of the second-order electric moment to infrared absorption is obtained with the help of a one-dimensional calculation, which is judged to be intrinsic and to be reasonably explained by a second order electric moment arising from charge deformation.

Theory of the First-Order Raman Effect in Crystals

TL;DR: The theory of the first-order lattice vibration Raman effect is given with particular reference to semiconductors in this article, where it is shown that the most important Raman scattering mechanism is always one in which the radiation interacts indirectly with the lattice via the electrons.
