COMMENTS: Absorption measurements for broadband ArF excimer radiation at 193 nm in shock-heated water vapor

Empirical fit for the absorption coefficient:

k193 nm = 51.3 × exp(-5400/T) × [1 - exp(-5400/T)] × (300/T)

converted to absorption cross sections using factor RT = 1.36×10-22 T; R (gas constant) in cm3 atm molecule-1 K-1
