DATAFILE: HC(O)C(O)OH_BackYamamoto(1985)_355K_221.3-407.2nm.txt
NAME: glyoxylic acid
FORMULA: HC(O)C(O)OH
AUTHOR(YEAR): BackYamamoto(1985)
T: 355K
λ: 221.3-407.2nm
BIBLIOGRAPHY: R.A. Back and S. Yamamoto, "The gas-phase photochemistry and thermal decomposition of glyoxylic acid", Can. J. Chem. 63, 542-548 (1985); DOI: 10.1139/v85-088
COMMENTS: Low-resolution spectra were obtained with a Heath modular double-beam spectrophotometer modified to take a 4 m heated absorption cell

Extinction coefficients vs. wavelength depicted in Fig. 1 have been digitized and converted to absorption cross sections (conversion factor 3.8235×10-21)
