NAME: methane
FORMULA: CH4
AUTHOR(YEAR): LeeChiang(1983)
T: 293K
λ: 121.567nm
BIBLIOGRAPHY: L.C. Lee and C.C. Chiang, "Fluorescence yield from photodissociation of CH4 at 1060-1420 Å", J. Chem. Phys. 78, 688-691 (1983); DOI: 10.1063/1.444812
COMMENTS: Absorption measurements in the 106 to 142-nm region using synchrotron radiation as a light source; spectral resolution 0.2 nm

The absorption cross section for the wavelength of the Lyman-α line has been estimated from Fig. 1 by
