Rate constants for reactions of CF3CF2CFHO2 radicals with NO and NO2 were k3 > × 10-12 and k4 = (6.3 ± 0.7) × 10-12 cm3 molecule-1 s-1, respectively. Using a FTIR spectrometer/smog chamber technique it was shown that, under atmospheric conditions, reaction with O2 and decomposition via C-C bond scission are competing loss mechanisms for CF3CF2CFHO radicals. A lower limit of 105 s-1 was deduced for the rate of decomposition of CF3CF2CFHO radicals via C-C bond scission at 296 K in 1 bar of SF6 diluent.
