Abstract
The hydrogen chloride infrared emission from the reactions of H atoms with OCl2, SCl2, S2Cl2, SOCl2, and SO2Cl2 has been studied under a variety of conditions. A limited number of experiments with the deuterium atom reactions also are reported. The emission from the highest vibrational level gave an estimate of the first sulfur–chlorine bond dissociation energy for these compounds. The emission intensities, relative to H+Cl2, from the various reactions were measured and were used to estimate relative rate constants, which decline through the series OCl2, Cl2, SCl2, S2Cl2, SOCl2, and SO2Cl2. Qualitative deductions about the energy partitioned to the HCl† product by the different reactions are presented.
