N2 - A pulse radiolysis technique has been used to measure a rate constant of (6.6±1.3) x 10-12 cm3 molecule-1 s-1 for the association reaction between CF3C(O)O2 radicals and NO2 at 295 K and one atmosphere total pressure of SF6 diluent. A FTIR/smog chamber system was used to study the thermal decomposition CF3C(O)O2NO2. The rate of decomposition of CF3C(O)O2NO2 was independent of the total pressure of N2 diluent over the range 100-700 Torr and was fit by the expression k-1=(1.9-1.5 +7.6)x1016 exp[(-14000±480)/T] s-1. Implications for the atmospheric chemistry of CFC replacements are discussed.
