science-softCon uv/vis+ spectra data base; www.uv-spectra.de, (C) science-softCon 2009 Substance: glyoxal Other Names: ethanedial Formula: C2H2O2 CAS-No.: 107-22-2 Study: uv quantum yields, photolysis Authors: K. J. Feierabend, J. E. Flad, S. S. Brown, J. B. Burkholder Title: HCO Quantum Yields in the Photolysis of HC(O)C(O)H (Glyoxal) between 290 and 420 nm Journal/Source: J. Phys. Chem. A, 113 (27), 7784-7794, (2009); DOI: 10.1021/jp9033003 Data: (diagram, table, disk): table, diagram Wavelength/Energy range: 290 - 420 nm Resolution: Temperature: 298 K Temperature dependence: Pressure/Concentration: 50 - 550 torr (N2) Comments: Quantum yields for the production of the formyl radical, HCO, in the photolysis of glyoxal were determined at 85 wavelengths in the range of 290-420 nm at pressures between 50 and 550 Torr (N2) at 298 K using pulsed-laser photolysis combined with cavity ring-down spectroscopy detection of HCO.
