Kinetic spectroscopic studies of alkyl, alkylperoxy and acetyl radicals Adachi, Hiroyuki
Abstract
The main objectives of this investigation are (i) the characterization of the absorption spectra of four radicals: the ethyl, methylperoxy, ethylperoxy and acetyl radicals, and (ii) the measurement of the rate constants of some of their characteristic rapid reactions. The spectral and kinetic measurements reported in this dissertation were made possible by an advance in experimental technique that increased the sensitivity of measurement of absorbance by an order of magnitude. This increase was achieved by a combination of (i) an increase in the intensity of the analytical light source by the application of a square wave voltage pulse, and (ii) the use of a dual beam optical system with balanced photomultipliers. The parameters that characterize the absorption spectra of the four principal radicals (and related species) are listed in Table-1. The rate constants measured for reactions of the four principal radicals (and related species) are listed in Table-2. [tables not included]
