science-softCon uv/vis+ photochemistry database; www.photochemistry.org; (C) science-softCon 2019 Substance: glyoxal Other Names: ethane-1,2-dione; ethandial Formula: C2H2O2 CAS-No.: 107-22-2 Study: photolysis, uv absorption cross sections Authors: Y. Chen, L. Zhu Title: Wavelength-dependent photolysis of glyoxal in the 290-420 nm region Journal/Source: J. Phys. Chem. A, 107, 4643-4651, (2003); DOI: 10.1021/jp022440d Data: diagram, table Energy/Wavelength range: 290 - 420 nm Resolution: 10 nm Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The authors have studied the gas-phase photolysis of glyoxal, (CHO)2, at 10 nm intervals in the 290-420 nm region by using dye laser photolysis coupled with cavity ring-down spectroscopy. Absorption cross sections of glyoxal have been measured. Author to whom correspondence should be addressed: (e-mail address):
