DECOMPOSITION OF HEXAFLUOROPROPYLENE OXIDE IN A STRONG IR FIELD

Multiphoton dissociation (MPD) of hexafluoropropylene oxide (HFPO) und er focused CO2-laser radiation was studied. A high-energy channel of H FPO decomposition was revealed. The dependences of the MPD yield and t he ratio between various channels of HFPO decomposition on the laser r adiation frequency in the range from 967.7 to 1090.0 cm(-1), the incid ent radiation energy, and the initial pressure of HFPO were obtained. A considerable contribution of thermal decomposition Of HFPO occurring outside of the irradiated zone to the total yield of its decompositio n was established. An explanation for the pressure dependence of the y ield of HFPO decomposition was suggested.
