COMMENTS: | Absorption measurements at 273, 296, 318, and 343 K and over the wavelength range 220-350 nm using a 0.5 m spectrometer with a 1024 element diode array detector and a 30 W D2 lamp light source; spectral resolution ∼1.5 nm
The temperature dependence has been parameterized by a simple two component absorption model:
σ(T, λ) = σ0(λ)/Q + σ1(λ)(1 - 1/Q), where Q = 1 + exp(-ΔE/(0.69T)) and ΔE = 988 cm-1.
The spectra have been scaled to the reported cross section data at 250-270 nm of
