Outline of Final Research Achievements

A novel method for studying high temperature reaction kinetics has been developed and applied to some high temperature reactions. In this method, transient absorption spectra of shock-heated sample gases are recorded by using broadband cavity-enhanced absorption spectroscopy technique. Kinetics of thermal decomposition reaction of nitrogen dioxide and formation and decomposition reactions of formaldehyde have been studied by using the method developed. The results demonstrated the applicability of the method to kinetic studies of high-temperature reactions. The method has also been applied to investigate the high-temperature reactions of nitromethane, benzyl radical, and anisole, for which new kinetic and mechanistic insights have been obtained.
