β¦ Synopsis
Iser-based clwmicsl kinetics technique has been demonstrated in studies of the reaction of 011 with C2114_ The rcxtwn mcchnism is dominated by elcctrophtlic addition of OH to the double bond at low temperatures, and by increasing-I\ rApid decomposition of the thcrmalized adduct iiOC2t-l.~ back to reactants as the temperature is raised.

CFBr radicals produced by the reaction of atomic oxygen with FzCCFBr were monitored in a discharge flow system by fluorescence excited at 424 nm. The rate coefficients for reactions of the CFBr radicals were measured between 298 and 358 K, and the following values were obtained in units of cm3/molec
HSiF has been detected by laser-induced fluorescence, following the formation of the ground-state radical in the flow reaction of SiH2 with Fz at a total pressure of 0.05-0.15 Ton. We report here the radiitive life-tie of the fust vibronic state of HSiF (A 'A") as well as a tentative assignment of
Laser-mduced fluorescence of the x 'A"-% 'A' transition in the gas-phase CHF radical has been observed, foBowing the fo\_rmatron of the ground-state radical by 1R multiple-photon dissociation. Radiative kfetimes of four vibroruc states of CHF (A 1 A") are reported. \* Throughout tius paper ape value
Dichlorosilylene, Sic12 , in the gas phase has been detected by laser-induced fluorescence of the x 'B1-?? 'Al transition in the 309-333 mn region. The wavenumber of the 0: transition is determined to be 30003.6 f 0.5 cm-' (333.20 nm). The fundamental vibrational frequencies are assigned to be IJ~ =
