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.
The title compound has been synthesised, and characterised by multinuclear magnetic resonance spectroscopy, both in solution and in the solid state. The bandshapes of variabletemperature solution-state 19 F NMR spectra have been iteratively fitted to obtain information on the kinetics of rotation ab
The following gas-phase reactions: (1) ( 2 ) were studied by the competitive method with CF,I as the source of radicals. The kinetic parameters obtained in the temperature range 533-613 K and 503-613 K respectively for chlorine atom transfer reactions are given by: log hl/h,"(cm3 mol-" s -") = 16
