Laser Studies of Halogens and Oxygen.
Abstract
Interconversions of energy between the metastable species of halogens, interhalogens, and oxygen are important to the determination of the mechanisms for the chemical oxygen/iodine and IF lasers and to the development of a better fundamental understanding of electronic energy transfer. Previous research by our group in this broad area has investigated the kinetics of the equilibrium I* + O2 = I + O2(1 Delta), has measured electronic-to-vibrational energy transfer from I* to I2, and has determined the rates of deactivation of I* by alkyl and perfluoroalkyl iodides. During the past three years our efforts have focused on better ways to detect O2 (1 Delta), on the deactivation kinetics of I* by Cl2, and on the photodisociative generation of iodine atoms. Sensitive detection of O2 (1 Delta by multiphoton ionization is reported. The deactivation of I* by Cl2is found to be much slower than previously thought. The photodissociation of ICN and CH3I have been examined. The relaxation of I* by alkyliodides and perfluoroalkyliodides is reported. Keywords: Electronic State Quenching; Vacuum ultraviolet.
