Kinetic Studies of Gas Phase Free Radicals.

Abstract

Detailed studies of elementary unimolecular and bimolecular gas phase processes were carried out using the time-resolved techniques of laser photolysis and laser induced fluorescence. Bimolecular reactions of diatomic and triatomic carbon and the ethynyl radical with small polyatomic molecules were investigated, and rate coefficients and energy disposal into product degrees of freedom were determined. The study of unimolecular reactions induced by multiple photon excitation concentrated on simple bond fission reactions. Nascent rovibronic state distributions in the dissociation products of trifluoroacetonitrile were determined as a function of laser fluence and intensity. The rate of the unimolecular reaction of 2-methyl-2-nitrosopropane was measured following dye laser excitation, and found to be faster than the rate deduced from thermal activation experiments.
