A transient absorption spectrum has been observed in the pulsed CO2 laser photodissociation of CFzBrz. This has been assigned to the intermediate CFsBr radical. The spectrum shows a broad band in the region of 220-320 nm with a maximum around 260 nm. The absorption cross section of CFzBr at 262 nm a

The COz-laser-induced IRMPD of CF2C12/HI and CF\*ClBr/HI mixtures produced "C-enriched CF,HCI. In CF#&/HI mixtures, the CF,HCI underwent secondary IRMPD in the continuing pulse irradiation at the same wavenumber and fluence, yielding CFzHz with a "C content of 97%. Because of efficient decomposition
A number of lines from a CO2 TEA laser were used to photolyze CF2C12. Enrichment of the 35C1 and "Cl isotopes in the molecular chlorine formed durmg the photolysis was observed using a mass spectrometer. Maximum enrichment was about 1.8. The dependence of enrichment on wavelength, reactant concentra
Reactions of CF2 carbene, generated by infrared CO1 laser photolysis of CHClF>, with Br2, Cl2 and Hz were investigated using infrared diode laser spectroscopy. Absolute rate constants at about 550 K for the reactions with Br2 and Cl\* were found to be (2.7+0.9)x10-I5 and (3Sf l.3)x10-'5cm3molecule '
Infrared diode laser spectroscopy was applied to the detection of CF2 carbene produced by C02-laser-induced dissociation of CHCIF2. Time-resolved spectra of CF2 in several rotation-vibration states were observed. The initial concentration of CF2 was estimated to be 5x IO" molecules cm-' from an anal
A variety of relative and absolute techniques have been used to measure the reactivity of fluorine atoms with a series of halogenated organic compounds and CO. The following rate constants were derived, in units of cm3 molecule-' s-l: CH3F, (3.7 2 0.8) X CH3C1, (3.3 2 0.71 X 10 -'I; CH3Br, (3.0 2 0.
