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

โฆ Synopsis
The reactions of F atoms with C2HSI, C2FSI, and n-CjHSI were studied by the crossed beam laser-induced fluorescence techniques within the 570-620 nm wavelength region. The vibrational and rotational excitation spectra of the reaction product IF were measured. The relative vibrational population densities of v= 3,4, and 5 vibrational levels, and some of the relative detailed vibrational rate constants, the rotational temperatures, and the mean fractions of rotational energy in individual vibrational states of the reaction product IF were obtained. The reaction mechanism was discussed.
