Microscopic Rate Constants for D + F2,
Abstract
The vibrational energy distributions resulting from exoergic bimolecular exchange reactions of the type: A + BC yields - AB + C have been successfully determined by the Chemiluminescence Techniques. Specifically, nascent population distributions have been obtained using the Arrested Relaxation (AR) method in which the reaction takes place in a low pressure (< 1 micron), cold wall, fast pumping speed environment. Although the AR method has produced valuable information pertaining to energy distributions, the following modifications would be highly desirable so that 'undoable' reactions could be performed: (1) increase the atom concentration by effectively increasing the dissociation efficiency of the atomic precursor without the addition of an inert gas (the location of the microwave cavity is undesirably far from the orifice decreasing the effective molecular dissociation); (2) decrease reagent throughput so that reasonable pumping systems can be used; (3) eliminate wavelength dependence of baseline the lock in amplifier derives its output from the difference in emission between the copper blade (thermal) and the reaction vessel (thermal + chemiluminescence) so that the zero reaction signal depends on wavelength; (4) observe time evolution of the product distribution so that relaxation and secondary processes can be deconvoluted; (5) increase S/N by signal averaging; and (6) introduce data storage so that more efficient processing can be used.
