Molecular rotation and volume dependence of the thermal conductivity in liquid N₂

Abstract

The influence of molecular rotation on the volume dependence of thermal conductivity in liquid nitrogen was evaluated. A modified method of reduced coordinates has been used to calculate components of the isochoric heat capacity of liquid nitrogen. A difference in the behavior of temperature dependences of the Bridgman coefficient at pre-crystallization temperatures in liquid Ar, CH4 and N2 is explained by the influence of rotational motion of molecules.
