| COMMENTS: | Absorption measurements at 240, 260, 280, 298, 320, 340, and 360 K using a D2 lamp (30 W) coupled to a 0.25 m spectrometer equipped with a diode array detector Parameterization of the temperature dependence by σ(T, λ) = σ(298 K, λ) × exp[B × (T - 298)] The absorption cross sections have been calculated using absorption cross sections measured at 298 K, the paramerization and the temperature coefficients: --------------------
