Rotational Motion of Molecules and Structural Transitions in Liquid Pyridine

Abstract

The temperature dependence of the anisotropic component intensity of molecular scattering of light and the contour shape of the anisotropic part of scattering have been measured. The anomalous behavior of the integral intensity of the anisotropic component of molecular scattering of light on temperature has been established. It has been shown that the regularities observed in scattering can be interpreted based on a mechanism of hindered rotation of molecules with taking into account the specifics of intermolecular interaction in pyridine.
