Paper Abstract

This paper is a continuation of our previous study of actual trajectories in calculation of a first-order term of an interruption function determining a shift of rovibrational lines in the short-wave region. The method based on exact solutions of classical equations of motion is used for calculation of resonance functions of the anisotropic part of the potential which determines second-order terms of the interruption function. Our investigations show that an account of the trajectory bending does not change the basic relations of the collision theory but requires redefining of the resonance function. The universal function of two arguments independent on the potential parameters and initial conditions of collision have been obtained. New resonance functions exhibit 'universality' since they depend on reduced interaction parameters. The approximation of the straight-line trajectories allowing us to obtain the same expressions as obtained by Leavitt is presented in the paper. Approximate calculations of resonance functions for the H2O-H2O and H2O-SO2 colliding particles have been made.
