| COMMENTS: | IUPAC(2006) recommendation: The preferred values of the absorption cross-sections at 298 K are based on the work of H.G. Libuda and F. Zabel, "UV absorption cross section of acetyl peroxynitrate and trifluoroacetyl peroxynitrate," Ber. Bunsenges. Phys. Chem. 99, 1205-1213 (1995); DOI: 10.1002/bbpc.199500061, and R.K. Talukdar, J.B. Burkholder, A.-M. Schmoltner, J.M. Roberts, R.R. Wilson, and A.R. Ravishankara, "Investigation of the loss processes for peroxyacetyl nitrate in the atmosphere: UV photolysis and reaction with OH," . Geophys. Res. 100(D7), 14163-14173 (1995); DOI: 10.1029/95JD00545, which agree to within a few percent at wavelengths below 290 nm and only slightly less well at longer wavelengths where the error limits on the measurements increase because of the difficulty of measuring the small cross-sections in that region of the spectrum. The temperature variation of the absorption cross-section at a particular wavelength in the range 196 nm to 344 nm is expressed as ln σ(T) = ln σ(298 K) + B × (T-298) with the temperature coefficients B for 250-298 K as obtained by Talukdar et al. (1995): -------------------
