Formulas are derived for the population of the upper vibrational state of a molecule excited by a square pulse of linearly or circularly polarized laser radiation that is in resonance with a definite vibrational-rotational transition. Numerical calculations of the behavior of the shape, half-width, and maximum absorption of the line contour as a function of the intensity, width, and polarization of the radiation pulse in models with strong collisions which deorient the molecule and in the absence of deorientation were performed. The qualitative features of the nonstationary saturated absorption are compared with existing experimental facts.
