COMMENTS: | Absorption measurements using a scanning monochromator equipped with a hydrogen discharge light source and a photomultiplier tube
Absorption constants k (atm, 298 K)-1 cm-1 (base e) have been digitized from Fig. 1 (logarithmic plot) and converted to absorption cross sections (conversion factor 4.06×10-20)
Remark: Fig. 1 only shows "absorption intensity in cm-1" vs. wavelength; obviously k (atm, 298 K)-1 cm-1 (base e) was measured as compared to the plotted "absorption intensity" for O3 from

Remark: The high absorption presumably is due to NO2 impurities |
