The trifluorovinyl radical (C2F3) is identified by using infrared spetroscopy.Real-time broadband infrared laser and diode infrared laser absorption spectra of the trifluorovinyl radical were measured.The radical was generated from UV laser photolysis of trifluoroiodoethene(C2F3I) at248 nm in the gas phase.The observed vibrational frequencies and intensities 2, 1290 (+/- 5) cm-1, 106 (+/- 39) km mol-1; and ν3, 1225 (+/- 5) cm-1, 119 (+/- 41) km mol-1> are in good agreement with ab initio values calculated in this work.Pseudo-first-order decay kinetics of the transient vibrational bands were observed.Analysis of the photoproducts with Fourier transform infrared spectroscopy showed that 1,3-hexafluorobutadiene (C4F6) was present in high concentration.It was probably formed from the reaction of trifluorovinyl radical with trifluoroiodoethene, as is consistent with the observed kinetics.

Photodissociation of trifluoroethylene (F2CCFH) at 157 nm has been investigated using photofragment translational spectroscopy. Four dissociation channels have been experimentally observed: molecular HF elimination, H atom elimination, F atom e
Competing pathways in the infrared multiphoton dissociation of hexafluoropropene

The infrared multiphoton dissociation of hexafluoropropene was studied by photofragment translational spectroscopy. Two primary channels and one secondary channel were identified. The predominant primary channel produces CF3CF or C2F4 and CF2, with the heavier species undergoing further dissociation to two CF2 fragments. A number of dissociation mechanisms are proposed for the elimination of CF2, including direct cleavage of the carbon - carbon double bond. In the second primary channel, a simple bond rupture reaction produces CF3 and C2F3. As expected, the translational energy distribution for this channel peaks near zero, indicating no exit barrier is present. The activation energy for this simple bond rupture is estimated to be 100-105 kcal/mol. The branching ratio, [CF2]/[CF3], between the two primary pathways is 4.0 ± 1.0.

Ground-state Ga(4p12P1/2) atoms are produced by visible multiphoton dissociation of trimethylgallium and monitored by resonance fluorescence excitation in a pulsed laser photolysis-laser fluorescence arrangement.Reactions
