The kinetics of the reaction F+FSO3+M->FSO2OF+M (1) has been studied by using an ArF excimer laser flash photolysis/visible absorption technique to monitor the disappearance of FSO3 radicals.He, N2, and SF6 were used as bath gases in pressures ranging from 5 to 600 Torr at 298 K; CF4 was used in the same pressures between 298 and 378 K.Reaction 1 was found to be in the falloff region between second- and third-order kinetics.The following limiting high- and low-pressure recombination rate constants have been determined at 298 K: krec,=(7.6+/-1.0)*10-11 cm3 molecule-1 s-1, krec,0=(4.1+/-0.5)*10-28, (5.2+/-0.7)*10-28, (1.1+/-0.2)*10-27, and (1.3+/-0.2)*10-27 cm3 molecule-1 s-1. krec, and krec,0 showed a temperature dependence of T0.23 and T-3.1 (M=CF4), respectively.With the krec, data and the known values of the high-pressure rate constant for FSO2OF thermal decomposition, the equilibrium constant and the thermodynamical parameters of the system were obtained.An analysis of the krec,0 with respect to energy-transfer properties was performed.In terms of the canonical version of the statistical adiabatic channel model, the krec, values lead to α/β=0.49 for the ratio between the looseness and the Morse parameters.Specific rate constants derived from our experiments are also discussed.
