DATAFILE: Cl2_Park(1976)_200-2200K_253.7nm(fit).txt
NAME: chlorine
FORMULA: Cl2
AUTHOR(YEAR): Park(1976)
T: 200-2200K
λ: 253.7nm(fit)
BIBLIOGRAPHY: C. Park, "Rates of reactions ClO + ClO → Cl2 + O2 and ClO + O → Cl + O2 at elevated temperatures", J. Phys. Chem. 80, 565-571 (1976); DOI: 10.1021/j100547a002
COMMENTS: Fit of the measured absorption cross sections from shock-tube experiments (303-2093 K):

σ = (1 - e-807/T) ∑σv e-807v/T (v = 0-19) with

σv = (4.5 + 37v + 15v2) × 10-22 cm2 molecule-1

v = vibrational quantum number
