DATAFILE: CH4_Reilhac(1969)_298K_11.1-42.7nm.txt
NAME: methane
FORMULA: CH4
AUTHOR(YEAR): Reilhac(1969)
T: 298K
λ: 11.1-42.7nm
BIBLIOGRAPHY: L. de Reilhac, N. Damany-Astoin, and J. Romand, "Mesure des coefficients d'absorption des gaz dans l'ultraviolet extrême", Spectrochim. Acta A: Mol. Spectrosc. 25, 19-30 (1969); DOI: 10.1016/0584-8539(69)80167-4
COMMENTS: Absorption measurements by photographic spectrometry using a grating spectrograph and a spark produced by an uranium anode as a light source

Absorption coefficients k (atm, 273K)-1 cm-1 (base e) as plotted in Fig. 5 have been digitized and converted to absorption cross sections (conversion factor 3.72×10-20)
