Predissociation and Quenching Dynamics of Electronically Excited Hydroxyl Radicals
Abstract
A series of studies has been conducted to examine the sources and sinks of electronically excited hydroxyl radicals via photon-assisted, unimolecular, and collision-induced processes. Significant progress has been made on three different fronts: (1) simulation of ultraviolet emission data from the Space Shuttle's thruster plume as originating from solar-induced and collision-induced electronic excitation of hydroxyl radicals; (2) detection of hydroxyl radicals in various vibrational levels of the ground electronic state through photoionization via high-lying Rydberg states; and (3) examination of the photodissociation dynamics of highly vibrationally excited hydroxyl radicals at specific ultraviolet wavelengths (243 and 226 nanometers).
