Laser Studies of Gas Phase Radical Reaction.
Abstract
Preliminary Lithium Fluoride (LIF) studies of CF are now almost complete. High quality spectra have been obtained, rotational constants have been refined, and lifetime studies are nearing completion. Infrared emission from the reaction 0 + CHF = products has been observed, although the weakness of the signal has prevented wavelength resolved measurements through a monochromator from being carried out. The CHF radical was formed by pulsed laser irradiation, and the kinetic behavior of the total emission has been studied as a function of both oxygen atom and CH2F2 radical precursor concentrations. It appears that the relatively high precursor pressures needed to observe emission are complicating the reaction scheme expected from previous studies of the vacuum uv emission accompanying this reaction. We are starting experiments using a range of ir filters in order to identify the emitting species.
