Comments:   Rate constant was determined relative to C2H5 + O -> Products, for which a value of 1.04x1014 cm3 mol-1s-1 was used (Hoyermann, K.; Olzmann, M.; Zeuch, T. Proc. Combust. Inst. 2002, 29, 1247).

Carbon centered radicals R were produced from the reaction of F atoms (microwave discharge of F2/He) with the precursor RH species: RH + F -> R + HF. O atoms were produced via the microwave discharge of O2/He mixtures. The R radicals were detected by time of flight mass spectrometry with laser induced multiphoto ionization at 433 nm. The relative decay rates of the R species were followed and used to derive the relative rate constants.
