COMMENTS: There appear to be no measurements of the gas-phase UV/visible absorption spectrum of butene-2-dial, but the absorption spectrum recorded by

D.L. Hufford, D.S. Tarbell, and R. Koszalka, "Maleic and fumaric dialdehydes, Δ4-tetrahydrophthalaldehyde and related compounds", J. Am. Chem. Soc. 74, 3014-3018 (1954); DOI: 10.1021/ja01132a018,

in iso-octane solution resembles the gas phase spectrum of the related compound: 4-oxo-pentene-2-dial

The relative absorption coefficients extracted from Fig. 1 of this work were scaled to the absolute gas phase cross-section σ(248 nm) determined by

Y. Tang and L. Zhu, "Photolysis of butenedial at 193, 248, 280, 308, 351, 400, and 450 nm," Chem. Phys. Lett. 409, 151-156 (2005); DOI: 10.1016/j.cplett.2005.05.007,

to provide the recommended values of σ over the range 193 - 460 nm
