COMMENTS: Absorption measurements with a nitrogen-purged Cary 14 ultraviolet spectrometer and a temperature controlled absorption cell equipped with a cooling jacket and Suprasil quartz windows

σ(T)/σ(296 K) values plotted in Fig. 2 have been digitized and multiplied by the absolute values for 296 K
