Abstract
Theory of the impurity-induced Raman scattering in crystals with NaCl structure. It is shown that the first-order Raman effect is not produced by alteration of the mass defect but by change in the force constant.
Résumé
Théorie de la diffusion Raman induite par la présence d'impuretés dans les cristaux du type NaCl. On montre que l'effet Raman du premier ordre n'est pas produit par l'altération de la masse, mais par celle de la constante de force.
