DATAFILE: CH4_SunWeissler(1955)_295K_37-131nm.txt
NAME: methane
FORMULA: CH4
AUTHOR(YEAR): SunWeissler(1955)
T: 295K
λ: 37-131nm
BIBLIOGRAPHY: H. Sun and G.L. Weissler, "Absorption cross sections of methane and ammonia in the vacuum ultraviolet", J. Chem. Phys. 23, 1160-1164 (1955); DOI: 10.1063/1.1742205
COMMENTS: Absorption measurements with a grazing incidence vacuum spectrograph and a condensed ac arc discharge as a light source

Absorption coefficients k (atm, 273K)-1 cm-1 obtained from six photographic plates and listed in Table II have been conversed to absorption cross sections (conversion factor 3.72×10-20)
