DATAFILE: HOC(O)C(O)OH_Back(1984)_403-413K_240-320nm.txt
NAME: oxalic acid
FORMULA: HOC(O)C(O)OH
AUTHOR(YEAR): Back(1984)
T: 403-413K
λ: 240-320nm
BIBLIOGRAPHY: R.A. Back, "The ultraviolet absorption spectrum of oxalic acid vapor", Can. J. Chem. 62, 1414-1428 (1984); DOI: 10.1139/v84-241
COMMENTS: Absorption measurements at low-resolution with a double-beam spectrophotometer

Absorbances vs. wavelength plotted in Fig. 1 have been digitized and normalized to the measured maximum value ε = 25 L mol-1 cm-1 (σ = 9.56×10-20 cm2 molecule-1) at 277 nm
