COMMENTS: Absorption measurements using a deuterium lamp as a light source and a dual beam diode array spectrometer with a spectral resolution of 0.3 nm

Data at 5-nm intervals from Table 1

A plot for the temperature dependence

log10 σ = log10 σ0 + B × T

gives for the intercept σ0 and the slope B (= temperature coefficient):
