DATAFILE: CH3CHO_Wang(2013)_500-1700K_306.74nm(fit).txt
NAME: acetaldehyde, ethanal
FORMULA: CH3CHO
AUTHOR(YEAR): Wang(2013)
T: 500-1700K
λ: 306.74nm(fit)
BIBLIOGRAPHY: S. Wang, D.F. Davidson, and R.K. Hanson, "High-temperature laser absorption diagnostics for CH2O and CH3CHO and their application to shock tube kinetic studies", Combust. Flame 160, 1930-1938 (2013); DOI: 10.1016/j.combustflame.2013.05.004
COMMENTS: "Best fit" of the measured absorption cross sections:

σ(T) = -1.88e-20 + 8.43e-23 T - 2.14e-26 T2 (T in K)

The erroneous equation given in the publication has been corrected by Shengkai Wang (personal communication, May 2016)
