The homogeneous rate of recombination of CFs radicals at 300 K was studied in a very-low-pressure photolysis flow reactor. The radicals were generated from CFsI by either CO, laser (1076 cm-') or excimer laser (248 nm) photolysis. The precursor and product concentrations were followed by mass spectr

## Abstract The relative rate technique has been used to determine the rate constants of the reactions of OH radicals with CF~3~CClο£ΎCCl~2~ (__k__~1~), CF~3~CClο£ΎCClCF~3~ (__k__~2~) and CF~3~CFο£ΎCFCF~3~ (__k__~3~). Experiments were carried out at (298Β±2) K and atmospheric pressure using ultrapure nitr
Hydrogen abstration from H,S by CF, radicals, generated by the photolysis of both CF,COCF, and CF,I. has been studied in the temperature range 314-434 K. The rate constant, based on the value of lo', 36 cm3/mol . s for the recombination of CF, radicals, is given by log h, = (12.20 I 0.05) -(19,220 2
The hydrogen transfer reaction between C2H6 and CFs radicals, generated by the photolysis of CF31, has been studied in the temperature range 298-617 K. The rate constant, based on the value of 1013 36 cm3 mo1-l s-' for the recombination of CFs radicals, is given by log kp = (11.90 2 0.09) -(33230 \_
The linear absorption cross-sections and photodissociation quantum yields for C F 3 N 0 have been measured at the wavelengths 694 3 and 632 8 nm (ruby and He-Ne lasers respectively) in a wide range of total pressure at T = 296 K The secondary reactions following the photolysis of C F 3 N 0 have been
