Calculation of absolute concentrations of SH and SO from their e.s.r. spectra

L. T. Cupitt and G. P. Glass


Transition probabilities have been calculated for several lines in the gas phase, X-band e.s.r. spectra of SH and SO, and the results of the calculations have been used to estimate the absolute concentration of the two free radicals in the gas phase. The concentration of SO obtained in this manner has been compared with the results of experimental measurements that were made by titrating mixtures of SO and atomic oxygen with nitrogen dioxide. During the course of this study, the relative rate constants for reactions (a) and (b) were measured: [graphic omitted] ka/kb was estimated as 0.63 ± 0.06.
