The high-temperature UV absorption and the recombination of CF3 radicals have been investigated in shock-wave experiments.CF3 radicals were produced near 1300 K in the fast dissociation of (CF3)2N2 and of CF3NO.At pressure of the bath gas Ar between 0.3 and 25 atm, the recombination was found to be in the unimolecular falloff range closer to the high than to the low pressure limit.Extrapolation to the high pressure limit gives k_rec,infinite(CF3)=(1.9+/-0.9)E13 cm³ mol^-1 s^-1 at T=1300 K.Earlier low-temperature results are compared with the present data by using unimolecular rate theory.
