Density Function Theory (DFT) B3LYP method was employed to study the mechanism of the reaction of CF3O2 radical and NO with the 6-31G、6-311G、6-311+G(d) basis sets. The study results indicate that there are three reaction pathways in this reaction. The main reaction pathway is CF3O2+NO→IM1→TS1→IM2→TS2→CF3O+NO2, the corresponding activation energy is 70.86 kJ•mol-1. The other reaction pathways are CF3O2+NO→ IM1→TS3→ CF3ONO2 and CF3O2+NO→TS4→IM3→TS5→IM4→TS6→CF3O+NOO, the corresponding activation energies are 258.71 kJ•mol-1 and 278.60 kJ•mol-1, and these reaction pathways are difficult to carry out. The results show that the main products are CF3O and NO2, which is in agreement with the results in literatures.
