PHOTOLYTIC AND PYROLYTIC FREE RADICAL STUDIES.

Abstract

The objective of the research was to devise means of observing reaction mechanisms in gases and vapors at elevated temperatures, particularly with systems involving metals and metal halides. A flash photolysis system was constructed to permit observation of species with life-times in the microsecond range and very low concentration. Spectrographic equipment covers the range from about 1200 Angstroms to the red end of the visible region. As a supplement to the spectrographic system, a mass spectrometric procedure is used to assist in identifying species in the high temperature metal halide systems. It was applied to identifying the vapor phase species in hot lead chloride vapor alone and in presence of HCl gas oxygen. (Author)
