摘要：
Н2О and СО2 continuum absorption within the IR absorption bands depends on the frequency boundaries within which the local line contribution is accounted for. Correlation between the maximal value of this boundary and the line shape at large frequency detuning is observed for the 4.3-, 2.7-, 1.4-, and 1.2-μm СО2 bands, as well as for rotational and 1400–1900-, 3500–3900-, and 5200–5500-cm−1 Н2О bands. The continuum absorption can be unambiguously determined from measurements in the band wings if one assumes that it is purely continual there. Within bands, the continuum absorption cannot be determined unambiguously and depends on the local line contribution boundary chosen. © 2018, Pleiades Publishing, Ltd.
