โœฆ Synopsis


Abstract

A novel technique is described for forming groundโ€state SO X^3^ฮฃ^๏ฃฟ^ radicals free of reactive impurities in a dischargeโ€flow system. Mass spectrometric detection of SO and ClO free radicals has been used to study the kinetics of the following reactions at 295 K:

## Abstract The rates of several novel elementary reactions involving ClO, BrO and SO free radicals in their ground states were studied in a dischargeโ€flow system at 295 K, using mass spectrometry. The rate constant __k__~2~ was determined from the decay of SO radicals in the presence of excess ClO
