Absolute Reaction Rate Constants of CFCl X1(A1) Reactions with Nitrogen Oxides
Journal of Physical Chemistry
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 apparaent 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)x10-14cm3molecule-1s-1. Decay rates of CFCl(X1A1,000) 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)x10-15 and (1.6±0.2)x10-14cm3molecule-1s-1, respectively, obtained at room temperature and 100-torr total pressure.
