Notes:
Photofragment translational spectroscopy of CBrClF2 at 157.6 nm was carried out using a crossed laser-molecular beams technique. Detected species are Br, Cl, and CF2. From the analyses of time-of-flight (TOF) spectra for these three species, the molecules were found to dissociate competitively through CBrF2+Cl, CClF2+Br, and CF2+Br+Cl channels with the branching ratio of 1.0:1.6−0.22+0.13:0.87−0.18+0.13. All of the CClF2 and CBrF2 radicals were found to dissociate spontaneously to produce Cl or Br+CF2, respectively. The angular distributions of these secondary products were found to be anisotropic. These fast secondary reactions are discussed on the basis of the calculated dissociation rates and rotational frequencies. © 2001 American Institute of Physics.
