Abstract

Calculations of collision-induced absorption spectral moments 1 and 1 for N2 and CO2 molecular pairs are presented which, for the first time, fully account for the anisotropic components of the intermolecular potentials. The results of these rigorous computations, performed at selected temperatures, are compared with approximations based on the perturbative approach and the infinite-order sudden approximation. In this way both important aspects of the effects of an anisotropic interaction and the ability of these two approximations to take them into account are demonstrated. © 1992 The American Physical Society.
