Energy Transfer Processes in Molecular Collisions.

Abstract

The purpose of the work was to analyze inelastic energy transfer processes by means of a rigorous theoretical method. It consisted of the following tasks: (1) Obtain temperature-dependent relaxation times for pure HF and DF, and HF and DF with CO2 as collision partners. (2) Calculate transition probabilities among higher vibrational states. (3) Calculate the criteria for dimer formation. (4) Investigate energy transfer in reactive collisions between F and H atoms with HF molecules. The method entails the rigorous solution of the two-dimensional equations of motion of two colliding molecules. Independent atom-atom potentials describe the interaction. Multipole interactions are based on experimentally determined energy values. Computer solutions yield the collision trajectories; subsequently, the energy transfer probabilities are evaluated for each degree of freedom. (Modified author abstract)
