A laser flash photolysis-resonance fluorescence technique has been employed to study the kinetics of the reaction of O(3P) with CF3NO (kz) as a function of temperature. Our results are described by the Arrhenius expression k z ( T ) = (4.54 ? 0.70) X 10-12exp[(-560 i 46)/T] cm3molecule-'s-' (243 K 5
The kinetics of the gas-phase reaction of C1 atoms with CF31 have been studied relative to the reaction of C1 atoms with CH4 over the temperature range 271-363 K. Using k(C1 + CH4) = 9.6 X exp(-2680/RT) cm3 molecule-' s-', we derive k(C1 + CF3I) = 6.25 X lo-'' exp(-2970/RT) in which E , has units of
Ab-initio computations at 298.15 K were made of the activation quantities AH\*, AS\*, and AG\* and of the reaction quantities AH r and AS r for is the transition state (TS). GAUSS-IAN92 was used and energies computed at a slightly modified Gaussian-2 level. Two potential surfaces for the TS had sym
