NAME: 4-oxo-2-pentenal
FORMULA: CH3C(O)CH=CHC(O)H
AUTHOR(YEAR): IUPAC(2012)
T: 294K
λ: 193-460nm(cis-trans)(rec)
BIBLIOGRAPHY: M. Ammann, R. A. Cox, J. N. Crowley, H. Herrmann, E. Jenkin, V.F. McNeill, A. Mellouki, M. J. Troe, T. J. Wallington, "Task Group on Atmospheric Chemical Kinetic Data Evaluation – Evaluated Kinetic Data", http://iupac.pole-ether.fr
COMMENTS: IUPAC(2012) recommendation:

A simple average of the recommended values for the cis- and trans-isomers, from

B. Xiang, L. Zhu, and Y. Tang, "Photolysis of 4-oxo-2-pentenal in the 190-460 nm region," J. Phys. Chem. A 111, 9025-9033 (2007); DOI: 10.1021/jp0739972,

applies to a 50:50 mixture of cis/trans isomers, which corresponds approximately to an equilibrium mixture for ambient conditions
