EFFECT OF VECTOR CORRELATIONS IN ROTATIONAL-TRANSLATIONAL EXCHANGE ON THE OPTICAL ANISOTROPY OF MOLECULAR COMPLEXES IN THE GAS
Abstract
A model of the formation of rotationally nonequilibrium ensembles of molecular complexes in the gas phase is developed taking into account the vector dynamics of translational-rotational exchange and its manifestation in the anisotropy of light absorption and emission. On the basis of the proposed model, the optical anisotropy of the ensemble of molecular complexes is calculated depending on the magnitude of the change in partial angular moments and the ratio of the moments of inertia of the initial fragments and the resulting complexes. It is shown that the increase in the value of the additional angular momentum, due to the moments induced during the rotational-translational exchange, can cause both a decrease in anisotropy and its increase depending on the shape of the ellipsoids of inertia of the complexes.
