Reaction:   FC(O)OO(O)CF + ·F → FC(O)OF + FC(O)O·
Reaction order:   2
Temperature:   295 K
Pressure:  1.33E-2 - 1.01 bar
Rate expression:   1.5x10-15 [±5.0x10-16 cm3/molecule s]
Category:  Experiment
Data type:   Derived from fitting to a complex mechanism
Pressure dependence:   None reported
Experimental procedure:   Static or low flow - Data taken vs time
Excitation technique:   Flash photolysis (laser or conventional)
Time resolution:   In real time
Analytical technique:   Vis-UV absorption
Comments:   This reaction is an assumed reaction to account for a double exponential fall in the decay of FC(O)O, where this reaction slowly produces FC(O)O. It is not a direct measurement.

This is a combined experimental and computational study of the reaction of FC(O)O radicals. Ab initio G3 calculations were used to look at the energetics of the possible reaction pathways. Typical total pressures were 30-747 torr He, 17-201 torr CF4, 10-81 torr FC(O)OO(O)CF. Temperature was 295(2) K. FC(O)O and F radicals produced by 193 nm excimer laser photolysis of FC(O)OO(O)CF. FC(O)O radicals detected in real time using absorption at 545 nm from a Xenon arc lamp.
