science-softCon uv/vis+ spectra data base; www.uv-spectra.de; (C) science-softCon 2010 Substance: tetrafluorosuccinic anhydride Other Names: 3,3,4,4-tetrafluorodihydrofuran-2,5-dione Formula: C4F4O3 CAS-No.: 699-30-9 Study: photolysis, quantum yields Authors: D. E. Weibel, E. R. de Staricco, E. H. Staricco Title: Quantum yield dependence on the wavelength in the gas phase photolysis of perfluorosuccinic anhydride Journal/Source: J. Photochem. Photobiol. A: Chem., 49 (3), 279-285, (1989); doi:10.1016/1010-6030(89)87126-6 Data: (diagram, table, disk): Energy/Wavelength range: 220, 232, 254 nm Resolution: Temperature: Temperature dependence: Pressure/Concentration: 3.0 - 70.2 Torr Phase (gas, liquid, solid): gas pH: Comments: The photolysis products were CO, CO2 and C2F4. 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.
