COMMENTS: | Recommendation based on the data of R.A. Cox and J.P. Burrows, "Kinetics and mechanism of the disproportionation of HO2 in the gas phase," J. Phys. Chem. 83, 2560-2568 (1979), J.N. Crowley, F.G. Simon, J.P. Burrows, G.K. Moortgat, M.E. Jenkin, and R.A. Cox, "The HO2 radical UV absorption spectrum measured by molecular modulation, UV/diode-array spectroscopy," J. Photochem. Photobiol. A: Chem. 60, 1-10 (1991), and M.M. Maricq and J.J. Szente, "A kinetic study of the reaction between ethylperoxy radicals and HO2," J. Phys. Chem. 98, 2078-2082 (1994) The data were fitted to a modified Sulzer-Wieland function σ = (σmed/(1 - b/ν) exp{-a [ln ((ν - b)/(νmed - b))]2} which yielded σmed = 1.64×10-18 cm2 molecule-1, νmed = 50260 cm-1, a = 4.91, and b = 30612 cm-1 |
