Investigation of Heterodiffusion in Molecular Crystals by the Method of Raman Effect
Abstract
Description
Using a method of a Raman effect of light the heterodiffusion in molecular crystals is investigated by the example of p-dichlorobenzene in a p-dibromobenzene. The installation diagram and a procedure of a determination of diffusivities using this method is given. Changes of diffusivities in a cut of a crystal perpendicularly to a direction of diffusion are found. Obtained values of diffusivities are in good agreement with those obtained by other methods.
