Line shape in the low-frequency wing of N(2) and O(2) broadened CO(2) lines.
The shape of the far wings of N(2) and O(2) broadened CO(2) lines have been investigated, at room temperature, in the 2140-2250-cm(-1) spectral region, i.e., on the low wavenumber side of the lines of the most intense band (nu(3) of (12)C(16)O(2)). The experimental results have been compared with calculated values based on the AFGL 1982 compilation. From this comparison it appears that the wings of the lines on the low wavenumber side of the centers decay much more rapidly than do Lorentz lines, by about the same amount as has been previously shown for the high wavenumber side. However, an asymmetrical correcting line shape factor is needed to obtain good agreement between experimental and synthetic spectra for wavenumbers sigma less, similar 2190 cm(-1).
