Infrared Multiphoton Dissociation Of Hexafluoroethane

The infrared multiphoton dissociation (IRMPD) of "neat" hexafluoroethane has been investigated for the first time. The stable products of photolysis are measured by IR absorption spectroscopy with a tunable lead-salt diode laser (TDL), which offers high sensitivity combined with a non-destructive measuring technique. The high sensitivity and resolution of the TDL allow measurement of the major stable products CF4 and C2F4 after irradiation by a single infrared laser pulse. A mechanism of IRMPD of C2F6 is proposed.
