Abstract : The reaction of O(3P) with C2F4 proceeds by the reaction scheme: O + C2F4 yields CF2O + CF2; O + C2F4 yields C2F4O; 2CF2 yields C2F4; CF2 + C2F4 yields cyclo-C3F6; C2F4O + C2F4 yields CF2O + C-C3F6; C2F4O yields CF2O + CF2 where C2F4O is excited intermediate. The ratio k5/(k11 + k5) is 0.15 at 22 C and drops slightly as the temperature is raised. The CF2 radicals produced give the same values for k3/k2(1/2) as do singlet CF2 radicals produced in another system. (Author)
