DATAFILE: CH4_WilkinsonJohnston(1950)_303K_137.1-145.5nm(meas).txt
NAME: methane
FORMULA: CH4
AUTHOR(YEAR): WilkinsonJohnston(1950)
T: 303K
λ: 137.1-145.5nm(meas)
BIBLIOGRAPHY: P.G. Wilkinson and H.L. Johnston, "The absorption spectra of methane, carbon dioxide, water vapor, and ethylene in the vacuum ultraviolet", J. Chem. Phys. 18, 190-193 (1950); DOI: 10.1063/1.1747586
COMMENTS: Absorption measurements using vacuum fluorite spectrograph fitted with a hydrogen discharge tube as a light source

The measured data points (absorption coefficients k (atm, 273 K)-1 cm-1 (base e)) plotted in Fig. 1 have been digitized and converted to absorption cross sections (conversion factor 3.72×10-20)
