Abstract:

Influence of the trajectory bending on spectral shifts of rovibrational lines of molecules is studied. The first order term of the interruption function is calculated using rigorous solutions of the classical dynamic equations. A universal function of two dimensionless arguments that is independent of the parameters of intermolecular potential and the initial conditions of a collision is derived. This function enables one to account for actual trajectories in calculations. The errors of calculations caused by the use of a model of linear trajectories are estimated for the water vapor and methane spectral lines broadend by foreign gases.
