Decomposition of hexafluoropropynele oxide in a strong IR field

Article abstract of DOI:10.1007/BF00696708

Multiphoton dissociation (MPD) of hexafluoropropylene oxide (HFPO) under focused CO2-laser radiation was studied.A high-energy channel of HFPO decomposition was revealed.The dependences of the MPD yield and the ratio between various channels of HFPO decomposition on the laser radiation frequency in the range from 967.7 to 1090.0 cm^-1, the incident 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 decomposition was established.An explanation for pressure dependence of the yield of HFPO decomposition was suggested. - Keywords: multiphoton dissociation; hexafluoropropylene oxide; carbenes; thermal decomposition; MPD spectrum.
