Abstract

In the first part of this paper the general theory of relaxation parameters of the spectrum shape in the impact approximation was presented. Here we describe some simplifications, discuss the isolated line approximation and compare our results with the other methods of a spectral line half-width and center shift calculation. As an example, illustrative calculations of the ^qQ(J,K) doublets in the v₁ band of NH₃ self-broadening have been performed and the results are compared with the experiment.
