| COMMENTS: | Measurements of the absorption cross sections at 240, 260, 280, 315, 337, and 360 K relative to those at 298 K (using a diode array spectrometer with a resolution of ∼0.4 nm) The data for 337 K have been calculated using the absolute absorption cross setions measured at 298 K, the parameterization of the temperature dependence by σ(T, λ) = σ(298 K, λ) × exp[B × (T - 298)] and the temperature coefficients B: ---------------------
