Abstract
Elementary reactions involving ground-state SF(X2Π) radicals have been studied at 295 K in a discharge-flow system near 1 Torr‡ using mass-spectrometric detection with collision-free sampling. SF radicals were generated by the reaction of F(2PJ) atoms with OCS: F + COS [graphic omitted] SF + CO (1). Rate constants are reported for reaction (1) as well as for the bimolecular disproportionation of SF SF + SF [graphic omitted] SF2+ S (2a)k1=(1.81 ± 0.16)× 10–11; k2a=(2.52 ± 0.19)× 10–11 cm3 s–1(1σ). In addition, the N(4S)+ NO reaction has been studied as a reference reaction N + NO [graphic omitted] N2+ O and the following result obtained: k3=(2.03 ± 0.17)× 10–11 cm3 s–1(1σ).Keywords
