Emission from FCO in the Reactions of Ozone with Fluoroethenes
Toby, Sidney,Toby, Frina S.
, p. 4071 - 4073 (1981)
The gas-phase reactions of ozone with cis-1,2-difluoroethene, trans-1,2-difluoroethene, trifluoroethene, and chlorotrifluoroethene are all accompanied by light with a maximum intensity at approximately 425 nm.A partial vibrational analysis of this emission is presented and it is concluded that the emitting species is the FCO radical, as previously suggested.A comparison is made between the enthalpy changes of the primary reactions between ozone and the fluoroethenes and their correlation with the identity of the emitting species.The exothermicity of the reaction correlates with the chemiluminescent reaction channel.
Dissociations of Gas-Phase CHClF and CHCl2 Radicals and Cations following Collisional Electron Transfer. A Variable-Time Neutralization-Reionization and ab Initio Study

Variable-time neutralization-reionization mass spectrometry is used to generate CHClF(.) and CHCl2(.) radicals and to study their unimolecular dissociations within 0.4-4.1 μs.Loss of Cl(.) is a major dissociation of CHClF(.) following collisional neutrali

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
On the Reaction of CH2(a1A1) with HF

The insertion reaction of singlet methylene CH2(a1A1) into the strongest element-hydrogen bond, H-F, is investigated.CH2(a1A1) is generated by pulsed UV-laser photolysis of CH2CO.Its removal is directly monitored via LIF-detection.The experiments are carried out under first order reaction conditions at temperatures T = 295, 380, and 485 K.Second order rate constants are determined from plots of first order rate constants versus the partial pressure of HF.The expression k1 = (5.5 +/- 1.5) * 1013 * (T/295 K)(-0.5 +/- 0.5) cm3/mol s is derived for the rate constant of the total depletion of CH2(a1A1 0,0,0) with HF.Thus at room temperature the reaction is slower than the analogous reactions with NH3, H2O and HCl.For the isotopically substituted CD2(a1A1 0,0,0) with HF the following rate expression is determined: k2 = (1.0 +/- 0.3) * 1014 (T/295 K)(-1.0 +/- 1.0) cm3/mol s.The reaction of vibrationally excited CH2(a1A1 0,0,0) with HF has a room temperature rate constant of k3 = (2.0 +/- 0.4) * 1014 cm3/mol s.Fluorocarbene CHF is detected as primary reaction product by LIF.Thermochemical considerations show that formation of CHF is the only exothermic reaction pathway besides physical quenching of CH2(a1A1).
