Cross sections fOi rotational excitation'are calculated classically for coilisions ofH with CO and of He with HCN. The H+-CO cross sections are in good agreement with quantum results but the He+HCN results are not. Tix failure of the classical method, when applied to He+HCN, is attributed to the neg
If the collisional ionization is chiefly due to energy transfer from the polar-molcculc rotation to an electron in a high Rydberg state of the atom, then theory predicts that the cross section averaged over a thermal distribution of rotational states should show step-like structure as a function of
The results of classical trajectory calculations for rigid rotator p-Ha-p-Ha collisions are presented. Several trajectory methodologies are compared\_ Over the energy range for which quanta1 results are available classical-quanta1 comparisons are poor.
