The laser flash photolysis-absorption technique has been used to study the F+FCO+M->CF2O+M recombination reaction between 20 and 700 Torr of M=CF4 at 296 K.The values k_rec,0=(5.6+/-1.2)*10^-29 cm³ molecule^-1 s^-1 and k_{rec, infinite}=(7.9+/-1.1)*10^-11 cm³ molecule^-1 s^-1 were determined by extrapolation of the fall-off curve.An analysis of k_rec,0 with respect to energy-transfer properties has been carried out.The measured k_rec,infinite value is in reasonable agreement with the predictions of the simplified statistical adiabatic channel model.For the FCO+FCO<*> CF2O+CO reaction a rate coefficient of (2.1+/-0.2)*10^-11 cm³ molecule^-1 s^-1 was determined.
