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.
