Abstract:

The report consists of four rather independent sections. The first part gives a general survey of the use of the diffusion concept in chemical kinetics. The research performed under the contract is summarized and pertinent literature is reviewed. In the second part, relaxation times are calculated using a repulsive potential and heating the molecule as an harmonic oscillator. A mean value for the impact velocity is employed by averaging the velocity before and after the inelastic collision. In part three, rotational relaxation times are calculated by using a classical equivalent to Wang Chang and Uhlenbecks theory and assuming that the molecules rotate in the same plane during collision. The final part presents a quantum mechanical treatment of dissociation assuming impulsive interactions. The activation energy is assumed to be equal to the dissociation energy and the process is treated as a random walk on the energy levels of an unperturbed oscillator. Author
