Classical Calculations of H2O Rotational Excitation in Energetic Atomhyphen;Molecule Collisions

摘要

Classical rotational excitation probabilities for collisions of three atomic species with H2O have been calculated using a Monte Carlo procedure. The rigid rotor approximation for H2O is employed together with hard sphere scattering potentials permitting the excitation in a given collision to be calculated analytically. The results are applicable to high energylpar;ge; 1thinsp;eVrpar;collisions. A procedure for constructing differential rotational excitation cross sections is presented.
