Solving the line-shape problem with speed-dependent broadening and shifting and with Dicke narrowing. II. Application

Abstract

We apply the formalism presented in a previous paper to calculate spectra of an isolated line with speed-dependent broadening. The translational motion is modeled on a rigid-sphere interaction and includes the effect of the mass of the perturber on the profile. We show that the density, the mass of the perturber, and the ratio of the optical to kinetic cross section all play a role in revealing or concealing (in the profile) the effects of broadening, which depend upon the speed of the active molecule.
