Paper Abstract

The results of calculations of the H2O continuum absorption coefficients for IR spectra in 1000-1300 cm-1 and 2000-2700 cm-1 regions and absorption coefficients in the wings of the CO2 bands in the IR spectrum are presented. It is shown that the calculation of the local line contribution to the total absorption should be related to the line shape so that the maximum boundary of local line contribution does not fall into the region of frequency detunings corresponding to the exponential decay. The tendencies to a change of the continuum absorption with variations in the local line contribution boundary remain the same in cases of using both the experimental coefficient and calculated according the asymptotic line wing theory as the total absorption coefficient.
