NAME: methane
FORMULA: CH4
AUTHOR(YEAR): OBrienCao(2002)
T: 296K
λ: 755-940nm
BIBLIOGRAPHY: J.J. O'Brien and H. Cao, "Absorption spectra and absorption coefficients for methane in the 750-940 nm region obtained by intracavity laser spectroscopy", J. Quant. Spectrosc. Radiat. Transfer 75, 323-350 (2002); DOI: 10.1016/S0022-4073(02)00015-8
COMMENTS: Absorption measurements in the VIS/near-IR region (750-940 nm) at room temperature and 77 K using intracavity laser spectroscopy

Room temperature absorption coefficients in km-1 amagat-1 (base e) and averaged over 1-nm intervals have been digitized from Fig. 11 and converted to absorption cross sections (conversion factor 3.72×10-25)
