Eleven resonance functions are calculated in the exact trajectory model, which can be used for calculationof broadening coefficients ? of molecular lines during interactions with atoms of inert gases at verylow temperatures. These functions correspond to the atom-atom potential and the potential V(R, ?) writtenin terms of Legendre polynomials. The functions are represented in analytical form. The broadening coefficients? are calculated for absorption lines of CO perturbed by He and Ar at temperatures T from 300 to 2 Kusing the potential V(R, ?). It is shown that the dependence ?(T) for low temperatures T is determined by thepotential well depth. For the CO–He system, a comparison with the experimental data is performed.
