摘要
The rate constant k(5) of the reaction R(5) : CF3O + O-3 --> products has been measured at room temperature with the absolute Fast Flow tube technique in the pressure range 2-9 Torr. The CF3O radicals are generated by pyrolysis of the dimer CF3OOCF3 and their relative concentration is followed by Laser Induced Fluorescence. The CF3O/He mixture is flowed through the movable central injector whereas the reactant (ozone) is flowed into the main flow tube; this protocol allows a better control of the side reactions which compete with R(?)5. The average of our measurements leads to: k(5) = (1.3 +/- 0.5) x 10(-14) cm(3) molec(-1) s(-1) which is in reasonable agreement with the more recent determinations.
