Abstract

The interaction between diatomic molecules at finite temperatures is analysed with respect to their translational, rotational and vibrational motion. At low temperatures quantum diffraction phenomena associated with these motions affect the intermolecular potential. These effects disappear when the temperature rises to high values compared to some characteristic temperatures found for each of the three types of motion. In this limit it is a reasonable approximation to consider the intermolecular potential as a suitable average over all possible configurations of the nuclei of the molecules.
