science-softCon uv/vis+ photochemistry database; www.photochemistry.org; (C) science-softCon 2019 Substance: glyoxal Other Names: ethanedial Formula: C2H2O2 CAS-No.: 107-22-2 Study: photolysis, photoexcitation Authors: R.J. Salter, M.A. Blitz, D.E. Heard, M.J. Pilling, P.W. Seakins Title: New Chemical Source of the HCO Radical Following Photoexcitation of Glyoxal, (HCO)2 Journal/Source: J. Phys. Chem. A, 113, 8278–8285, (2009); doi:10.1021/jp9030249 Data: table Energy/Wavelength range: 395 - 414 nm Resolution: Temperature: 233 K; 298 K; 343 K Temperature dependence: yes Pressure/Concentration: Phase: pH: Comments: Photoexcitation of glyoxal at wavelengths over the range of 395-414 nm was observed to initiate a chemical reaction that produces the HCO radical in addition to the photolytic production of HCO.
