NAME: methane
FORMULA: CH4
AUTHOR(YEAR): Giver(1978)
T: 293K
λ: 434.7-529.3nm
BIBLIOGRAPHY: L.P. Giver, "Intensity measurements of the CH4 bands in the region 4350 Å to 10,600 Å", J. Quant. Spectrosc. Radiat. Transfer 19, 311-322 (1978); DOI: 10.1016/0022-4073(78)90064-X
COMMENTS: Laboratory measurements of the CH4 overtone bands using a 1200 line/mm grating installed in a scanning spectrometer and a quartz iodine lamp as a light source

The absorption spectrum shown in Fig. 2 (absorption coefficients in km-1 amagat-1 (base e) vs. wavenumber) has been digitized, and converted to absorption cross sections (conversion factor 3.72×10-25) vs. wavelength
