The measurement of infrared dispersion in solids by a method based on small particle scattering

A method of measuring the components of the complex index of refraction of solids near the reststrahlen region is described. The method is based on the scattering of electromagnetic radiation by small particles, and it is applied here to the cases MgO, LiNbO3, CdF2, and PbF2. © 1967 Optical Society of America.
