 Abstract: Experimental data from the literature for cross sections and rate constants for dissociative electron attachment to CF3Br, with separately varied electron and gas temperatures, are analyzed by a kinetic modeling approach. The analysis suggests that electronic and nuclear contributions to the rate constants can be roughly separated, the former leading to a negative temperature coefficient, the latter to a positive temperature coefficient. The nuclear factor in the rate constant is found to be of Arrhenius form with an activation energy which is close to the energy of crossing of the CF3Br and CF3Br− potential curves along the CBr bond.
