DATAFILE: CH2=C=O_DixonKirby(1966)_298K_320nm(max).txt
NAME: ketene
FORMULA: CH2=C=O
AUTHOR(YEAR): DixonKirby(1966)
T: 298K
λ: 320nm(max)
BIBLIOGRAPHY: R.N. Dixon and G.H. Kirby, "Absorption spectrum of ketene in the visible and near ultra-violet", Trans. Faraday Soc. 62, 1406-1410 (1966); DOI: 10.1039/TF9666201406
COMMENTS: The authors analyzed the absorption spectrum in the region 340-500 nm; absorption coefficients have not been measured

The quoted absorption maximum at 320 nm has been earlier measured by
