Abstract: Concentration dependence of basic light scattering quantities in ideal and real low-molecular mixtures was studied. Depolarization ratio alone may serve as a sensitive measure of the presence of specific interactions; on the basis of the course of this ratio one can speak about positive or negative deviations from Raoult's law. Experimental data of anisotropic scattering were in harmony with the idea that the parameters determining molecular orientation should be considered as continuous probability variables. Transition from one local structure to another with a maximum of concentration fluctuations and thus of isotropic scattering is indicated.
