COMMENTS: IUPAC(2006) recommendation:

The preferred values for the absorption cross-sections are based on those determined by

A. Horowitz, R. Meller, and G.K. Moortgat, "The UV-VIS absorption cross sections of the α-dicarbonyl compounds: pyruvic acid, biacetyl and glyoxal," J. Photochem. Photobiol. A: Chem. 146, 19-27 (2001); DOI: 10.1016/S1010-6030(01)00601-3,

which, except at λ < 240 nm, are in excellent agreement with the data of

J.J. Orlando and G.S. Tyndall, The atmospheric chemistry of the HC(O)CO radical," Int. J. Chem. Kinet. 33, 149-156 (2001); DOI: 10.1002/1097-4601(200103)33:3<149::AID-KIN1008>3.0.CO;2-1,

and in satisfactory agreement with the earlier data of

C.N. Plum, E. Sanhueza, R. Atkinson, W.P.L. Carter, and J.N. Pitts, Jr., "OH radical rate constants and photolysis rates of &a;-dicarbonyls," Environ. Sci. Technol. 17, 479-484 (1983); DOI: 10.1021/es00114a008
