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...read more

Raman investigation of high-pressure “disorder—order” phase transitions in NH4Br and NH4Cl
TL;DR: In this article, the spectrum of NH 4 Br V and the changes accompanying the NH 4 Cl V-IV transition are shown to be similar to the spectrum spectrum of disordered NH 4 4 Cl II-II and disorder-order NH 4 CL II-III phase transitions.

Raman scattering from sodium and silver in β-alumina
TL;DR: In this paper, it was concluded that diffusive conduction with a well-defined attempt frequency predominates up to 900°K and the frequency response is Lorentzian at all temperatures above 300°K with little change in frequencies and damping rates.

First-order Raman scattering in homoepitaxial chemical vapor deposited diamond at elevated temperatures
TL;DR: In this article, the polarization of the first-order Raman spectrum in homoepitaxial chemical vapor deposited diamond was measured for the temperature range 300-1200 K and the dependences of Raman shift and width on temperature for natural type IIa diamond over the temperature ranges 300-2000 K are also given for comparison.

Dynamical Theory of Crystal Lattices
Max Born,Kʿun Huang +1 more
TL;DR: Born and Huang's classic work on the dynamics of crystal lattices was published over thirty years ago, and it remains the definitive treatment of the subject as mentioned in this paper. But it is not the most complete work on crystal lattice dynamics.
