Cross Sections / Oxygen / O4 / ShardanandPrasadRao(1977)_300K_200-250nm

DATAFILE: O4_ShardanandPrasadRao(1977)_300K_200-250nm.txt
NAME: oxygen dimer
FORMULA: O4
AUTHOR(YEAR): ShardanandPrasadRao(1977)
T: 300K
λ: 200-250nm
BIBLIOGRAPHY: Shardanand and A.D. Prasad Rao, "Collision-induced absorption of O2 in the Herzberg continuum", J. Quant. Spectrosc. Radiat. Transfer 17, 433-439 (1977); DOI: 10.1016/0022-4073(77)90122-4
COMMENTS: The listed data are the cross sections σ2 derived from the measured (pressure dependent) absorption cross sections σeff and using the relation

σeff(l) = σ1(λ) + K σ2(λ) n(O2)

with K = equilibrium constant for O2 + O2 ↔ O4, n(O2) = number density of the gas
