COMMENTS: IUPAC(2008) recommendation:

The preferred values at 220 K for the wavelength range 190 nm to 220 nm are the mean of the values reported by

D. Gillotay and P.C. Simon, "Temperature-dependence of ultraviolet absorption cross-sections of alternative chlorofluoroethanes," J. Atmos. Chem. 12, 269-285 (1991); DOI: 10.1007/BF00048076; Aeronomica Acta A 358, 1-27 (1991),

J.J. Orlando, J.B. Burkholder, S.A. McKeen, and A.R. Ravishankara, "Atmospheric fate of several hydrofluoroethanes and hydrochloroethanes. 2. UV absorption cross sections and atmospheric lifetimes," J. Geophys. Res. 96(D3), 5013-5023 (1991); DOI: 10.1029/90JD02734, and

A.K. Nayak, T.J. Buckley, M.J. Kurylo, and A. Fahr, "Temperature dependence of the gas and liquid phase ultraviolet absorption cross sections of HCFC-123 (CF3CHCl2) and HCFC-142b (CH3CF2Cl)," J. Geophys. Res. 101(D4), 9055-9062 (1996); DOI: 10.1029/96JD00226

Because Nayak et al. did not report values for λ > 220 nm at their lowest temperature of 223 K, and the values of Orlando et al. at wavelengths greater than approximately 220 nm have been questioned by Gillotay and Simon, and by Nayak et al., the preferred values at 220 K and λ > 220 nm are the values reported by Gillotay and Simon
