Abstract:

Experimental data of some authors on the absorption coefficient of carbon dioxide in the cases of self–broadening and broadening by nitrogen of its spectral lines in the transmission microwindows and beyond the head of the 4.3 μm absorption band for temperature of 193 to 771 K and for pressure from the standard atmospheric to 60 Amagat are analyzed from the standpoint of the line wing theory. It is shown that the whole data set can be quite accurately described within the framework of this theory with the account for temperature behavior of the intermolecular interaction potential. Advantages and drawbacks of other theoretical approaches to description of spectral line wings are briefly discussed.
