Absolute rate constants of CFCI(X̃ < sup> 1 A < inf> 1 ) reaction with nitrogen oxides
The chlorofluoromethylene (CFCl) molecule has been generated from the infrared multiple-photon dissociation (IRMPD) of 1,2-dichloro-1,2-difluoroethylene (CFCl=CFCl) with an apparent nascent vibrational temperature above 300 K. The overall vibrational rate constant of CFCl for relaxation into v″ = 0 has been determined to be kv = (6.8 ± 0.7) × 10-14 cm3 molecule-1 s-1. Decay rates of CFCl(X̃1A1,000) with the stratospheric gases present in significant concentrations, N2, N2O, NO, NO2, and O2, are also reported. Of these substrate gases, only NO and NO2 were observed to have significant rates of reaction. The others were found to be relatively unreactive. The decay rate constants for reaction with NO and NO2 were found to be k = (8.7 ± 0.7) × 10-15 and (1.6 ±0.2) × 10-14 cm3 molecule-1 s-1, respectively, obtained at room temperature and 100-torr total pressure. © 1982 American Chemical Society.
