BIBLIOGRAPHY: M.A. Oehlschlaeger, D.F. Davidson, J.B. Jeffries, and R.K. Hanson, "Ultraviolet absorption cross-sections of hot carbon dioxide", Chem. Phys. Lett. 399, 490-495 (2004); DOI: 10.1016/j.cplett.2004.10.060
COMMENTS: Absorption measurements in mixtures of 2%, 5%, and 10% CO2 dilute in argon behind reflected shock waves

Fit of the measured absorption cross sections to the semi-empirical form

ln σ(λ,T) = a + bλ, where

a = c1 + c2T + c3/T,
b = d1 + d2T + d3/T

with the parameters

c1 = 0.05449, c2 = 0.13766, c3 = 23.529
d1 = 1.991, d2 = -0.17125, d3 = -14.694

T in 1000 K, λ in 100 nm, σ in 10-19 cm2 molecule-1
