Absorption measurements using a D2 lamp as the light source for the 33000-60000-cm-1 region, and microwave-powered Kr and Ar lamps for the 59000-80000-cm-1 region

Molar extinction coefficients vs. wavenumber plotted in Fig. 5 have been digitized and converted to absorption cross sections (conversion factor 3.8235×10-21) vs. wavelength
