Abstract
The Markovian theory of random processes is applied to describe collis ional relaxation of angular momentum as well as translational velocity simultaneously. It is shown by comparing exact and approximate soluti ons of the kinetic equation that in practical lineshape calculations t ranslational and rotational relaxation can be considered as statistica lly independent processes. The perturbation theory has been developed for the case of comparatively slight Doppler broadening.
