| COMMENTS: | IUPAC(2008) recommendation: The preferred values for the cross-sections at 298 K are based on the data for the absolute absorption cross-sections reported by M.E. Jenkin, T.P. Murrells, S.J. Shalliker, and G.D, Hayman, "Kinetics and product study of the self-reactions of allyl and allyl peroxy radicals," J. Chem. Soc. Faraday Trans. 89, 433-446 (1993); DOI: 10.1039/FT9938900433, O.V. Rattigan, D.E. Shallcross, and R.A.

Burkholder, G.K. Moortgat, A.R. Ravishankara, and P.J. Crutzen, "Temperature dependence of UV absorption cross sections and atmospheric implications of several alkyl iodides," J. Geophys. Res. 102(D11), 12819-12829 (1997); DOI: 10.1029/97JD00530. The listed values are actual values at 1-nm intervals. The temperature dependence ln σ(T) = ln σ(298K) + B × (T - 298) and the temperature coefficients B (243-333 K): --------------------
