Curriculum vitae FTIR smog chamber techniques have been used to show that reaction of CF3O2 radicals with NO proceeds via two channels giving either CF3O+NO2 (5a) or CF3ONO2 (5b) as products. In 700 Torr of N2/O2 diluent at 296 K the branching ratio for CF3 ONO2 formation is k5b/(1/k5a+k5b) =(1,67 @page { size: 209.99mm 296.99mm; margin: 20mm } P { margin-bottom: 2.12mm } -->± 0,27)  10 2. The CF3ONO2 forming channel is in the fall o
