| COMMENTS: | Recommendation for the HONO2 cross sections based on the own data and the data (except those at 238 K) of O. Rattigan, R.L. Lutman, R.L. Jones, and R.A. Cox, "Temperature-dependent absorption cross-sections of gaseous nitric acid and methyl nitrate," J. Photochem. Photobiol. A: Chem. 66, 313-326 (1992) Measurements at 240, 260, 280, 298, 315, 337, and 360 K,
parameterization of the temperature dependence by σ(T, λ) = σ(298 K, λ) × exp[B × (T - 298)] with the temperature coefficients B: ---------------------
