Quasi-Classical Calculations of Large Sets of Vibrationally Dependent Cross Sections for Atom-Molecule Collision Processes Involving Hydrogen, Nitrogen, and Oxygen

Detailed cross sections for atom€diatom collision processes involving hy- drogen, nitrogen, and oxygen, dependent on initial and ¦nal vibrational and rotational quantum numbers have been obtained quasi-classically. Starting from these complete cross section databases, many possibilities are o ?ered of detailed study of systems including the mentioned species, considering particularly translational nonequilibrium. Some aspects of these very intense calculations are illustrated, including an interpolation method presented here for the ¦rst time, developed for quasi-classical cross sections which can be extremely effective in reducing memory requirements in the successive use in numerical modeling. As a conse- quence of the availability of detailed data, termolecular recombination is treated with both detailed balance applied to dissociation data, and by orbiting resonance theory, with interesting results compared with some theoretical and experimental data from literature.
