Abstract

We discuss the application of time-resolved infrared spectral photography to the determination of the time-dependent reactant and product concentrations in the simple chain reaction of chlorine atoms, generated by pulsed photolysis, with ethane–Cl₂ mixtures. The technique and experimental results are discussed in terms of the limitations and advantages of the method for general kinetic studies in the microsecond and submicrosecond time domain.
