COMMENTS: Absorption measurements using hydrogen-discharge lamps as light sources and a VUV spectrophotometer

The extinction coefficient for the absorption maximum has been converted to the peak cross section (conversion factor 3.8235×10-21)

Remark of the authors:

"The spectral shapes obtained are in good agreement with those of

A.J.Harrison, B.J. Cederholm, and M.A. Terwilliger, Absorption of acyclic oxygen compounds in the vacuum ultraviolet. I. Alcohols, J. Chem. Phys. 30, 355-356 (1959): DOI: 10.1063/1.1729952,

and with those of

K. Watanabe and M. Zelikoff, Absorption coefficients of water vapor in the vacuum ultraviolet, J. Opt. Soc. Am. 43, 329, 753-755 (1953); DOI: 10.1364/JOSA.43.000753,

although our molar extinction values are 1.5 times to twice as large as theirs. The reason for this discrepancy is not clear"
