The temperature dependence of hydrogen abstraction reactions: F+HCl, F+HBr, F+DBr, and F+HI

Article abstract of DOI:10.1063/1.439088

A laser photolysis/infrared fluorescence technique has been used to study the temperature dependence of the F+HCl, F+HBr, F+DBr, and F+HI absolute rate constants in the range from 195 to 373 K.Multiphoton dissociation of SF6 with a TEA CO2 laser was used to provide a transient concentration of fluorine atoms.Their subsequent reaction with hydrogen donors was monitored by observing the appearance rate of HF(v>=1) through its infrared fluorescence.The observed rate constants show a marked nonlinear.Arrhenius behavior which is consistent with a model in which reaction takes place both via direct attack by the fluorine atom at the hydrogen end of HX and via formation of a collision complex FXH which rearranges to FHX and then dissociates to HF and X products.
