Bulletin of National University of Uzbekistan: Mathematics and Natural Sciences
As a result of the experimental study of the spectra of anisotropic scattering of light, a character of orientation movement of molecules in aromatic hydrocarbons has been analyzed. The obtained results have been interpreted from the viewpoint of a model of inhibited rotation and the contributions of the rotational and vibrational degrees of freedom to a molecule spectrum have been estimated. With increasing temperature of liquids under study and approaching a critical state, the rotational degrees of freedom "freeze", and the vibrational degrees have become more significant.

Scientific Journal of Samarkand University
The paper describes the principles of correlation spectroscopy of scattered light and a method for determining the size of particles suspended in a liquid using such spectroscopy - the method of dynamic light scattering (DLS). Some features of the application of the DLS method are considered.
