ABSTRACT

Green 1975

Green, S., 1975: Comment on the accuracy of Rabitz' effective potential approximation for rotational excitation by collisions. J. Chem. Phys., 62, 3568-3570, doi:10.1063/1.430949.

Cross sections for rotational excitation of HCN by low energy collisions with He have been computed with the effective potential approximation of Rabitz and compared with accurate quantum close-coupling results. Elastic cross sections are found to agree to about 20%; inelastic cross sections agree in general magnitude but not in detailed values for specific quantum transitions.
