✦ Synopsis

The UV and IR photolysis of trifluoroiodomethane and pentafluoroiodoethane in the presence of hydrogen were studied. The products were quantitatively analysed by IR spectrophotometry and temperature-programmed gas chromatography.

The photolysis product distribution using different experimental parameters was obtained. The difference between the product distributions in IR multiphoton dissociation (IRMPD) and conventional UV photolysis has been explained in terms of the various competing rate constants and the concentration of the perfluoroakyl radicals generated in the irradiated volume.
