✦ Synopsis

The photolysis of perfluorosuccinic anhydride vapour was studied in the pressure range 3.0 -70.2 Torr using light with wavelengths of 254, 232 and 220 nm. The products were CO, CO2 and C2F,: At higher pressures the quantum yield was 0.50 at all wavelengths, but at the zero pressure limit, the quantum yield at 254 and 232 nm was 0.74 and at 220 nm it was unity. The data are interpreted jn terms of a variation either in the vibrational level of the lowest excited singlet or in the electronic transition.
