Abstract

A line-by-line calculation of the continuum absorption coefficient with the wing line contour describing the absorption in different windows outside of the water vapor bands in the 4000–8000 cm^-1 spectral region is presented. The continuum absorption calculated with the line wing contour characterizing the absorption in the 5800–6400 cm^-1 window is shown to be close to the total absorption. Hence it follows that the absorption in the 5000–5500 cm^-1 and 6900–7700 cm^-1 bands is almost entirely due to metastable dimers and free complexes.
