摘要：

Using a pulse radiolysis UV absorption technique and subsequent simulations of experimental NO2 and FNO absorption transients, rate constants for reaction between CF3O and CF3O2 radicals with NO were determined, CF3O2+NO-->CF3O+NO2 (3), CF3O+NO-->CF2O+FNO (5). k3 was derived to be (1.68+/-0.26)x10(-11) cm3 molecule-1 s-1, and k5=(5.2+/-2.7)x10(-11) cm3 molecule-1 s-1. Results are discussed in the context of the atmospheric chemistry of halocarbons.
