The ultraviolet absorption spectrum of FO2 radicals and the kinetics of the reaction of F atoms with O2 have been studied in the gas phase at 295 K using pulse radiolysis combined with kinetic UV spectroscopy. At 230 nm, σFO2 =(5.08±0.70)×10-18 cm2 molecule-1. The kinetics of the reaction F+O2+M→FO2+M (1), were investigated over the pressure range 200-1000 mbar of SF6 diluent. At 1 atm total pressure the pseudo-second-order rate constant for reaction (1) was determined to be (1.9±0.3)×10-13 cm3 molecule-1 s-1.
