✦ Synopsis

A relative rate technique has been used to study the title reaction over the pressure range 100-700 Torr of air at 296 + 2 K. Four different reference compounds (13CO, CH4, CH2FCI, and CD 4) were used. Using k(CF30 + CH 4) = (2.2 -1-0.2) × 10-14 cm 3 molecule-1 s-1 a rate constant of k(CF30 + 03) = (1.5 + 0.5) × 10-14 cm 3 molecule-1 s-1 was derived, quoted errors reflect statistical and potential systematic errors. There was no observable effect of diluent pressure over the range 100-700 Torr. As part of the present work the rate constant for reaction of CF30 radicals with CH2FC1 was determined to be (1.2 + 0.2) × 10-14 cm 3 molecule-~ s-1. Implications for the atmospheric chemistry of CF30 radicals are discussed.
