Abstract

AbstractThe rates of several novel elementary reactions involving ClO, BrO and SO free radicals in their ground states were studied in a discharge‐flow system at 295 K, using mass spectrometry. The rate constant k2 was determined from the decay of SO radicals in the presence of excess ClO radicals: The SO + OClO overall reaction has a complex mechanism, with the primary step having a rate constant k5 equal to (1.9 ± 0.7) × 10−12 cm3 sec−1: A lower limit for the rate constant of the rapid reaction of SO radicals with BrO radicals was determined:
