Crossed Molecular Beam Study of the Reactions of Oxygen and Fluorine Atoms.
Abstract
Progress has been made in our understanding of oxygen and fluorine reaction chemistry through the study of several new reactions as well as the completed analysis of data obtained in the previous contract period. We have made further technological advances which will increase our ability to study O(3P) reactions and we have taken the initial steps to develop an O(1D) source. In the first three sections, the developments in the source technology and chemistry are discussed. First, in the photofragmentation spectroscopy of O3 to yield O(1D), the vibronic states of the dissociation product was resolved. Then, a discussion of the O(3P) source as used in the exciting studies of iodine abstraction reactions is presented. Lastly, we report the improvements which were made to increase the intensity, Mach number, and energy variability of the O(3P) source. Section four describes the completed high resolution of the reaction of O(3P) with IC1 and CF3I in which we were able to obtain an improved value of the IO bond energy. The reactions of C1 and F with C2H3Br, discussed in section five, contribute significantly to our understanding of the dynamics of chemical reactions. The nonstatistical product energy distributions and unexpected coupling of angular and energy distributions shed light on the mechanism of radical reactions and the importance of angular momentum.
