N2 - The ultraviolet-absorption spectrum and the self-reaction of CHF2O2 radicals have been studied in the gas phase at 298 K using the pulse radiolysis technique and long-pathlength Fourier transform infrared spectroscopy. Absorption cross sections were quantified over the wavelength range 220-280 nm. The measured cross section near the absorption maximum was σCHF2O2 (240 nm) = (2.66 ± 0.46) × 10-18 cm2 molecule-1. The absorption cross section data were used to derive the observed self-reaction rate constant for the reaction CHF2O2 + CHF2O2 → products, defined as d[R]/dt = 2k1obs[CHF2O2]2, k1obs = (5.0 ± 0.7) × 10-12 cm3 molecule-1 s-1 (± 2σ). The only carbon-containing product observed by FTIR spectroscopy was FC(O)F. These results are discussed with respect to previous studies of peroxy radicals.
