Cross Sections / Oxygen / O2 / Kley(1984)_298K_121.567nm

DATAFILE: O2_Kley(1984)_298K_121.567nm.txt
NAME: oxygen
FORMULA: O2
AUTHOR(YEAR): Kley(1984)
T: 298K
λ: 121.567nm
BIBLIOGRAPHY: D. Kley, "Ly(α) absorption cross-section of H2O and O2", J. Atmos. Chem. 2, 203-210 (1984); DOI: 10.1007/BF00114132
COMMENTS: Absorption measurements at a spectral resolution of 0.005 nm using a Ly(α) lamp (low-pressure radio frequency discharge through traces of hydrogen in argon)

The pressure dependence of the absorption cross section arising from the formation of O4 is
σ = σ0 + σ1 × P
σ0 is given in the datafile and
σ1 = (1.72 ± 0.21)×10-23 cm2 Torr-1
