Resonance functions for semiclassical molecular line broadening theory are calculated in the exact trajectory model for molecules environed by neutral gas atoms. The calculations are performed for a set of values of the Lennard-Jones potential parameters. Model analytic representations are constructed for resonance functions dependent on these parameters. The model functions are tested in the calculations of the scattering cross section of rotational lines of the HCl molecule in the system HCl-Ar and rotational line half-widths of the radical OH in the system OH-Ar.
