Abstract
This paper reports the design of the spectroscopic complex at IAO SB RAS for investigation of the absorption spectra in a wide spectral range (from 500 to 40000 cm-1) with a high sensitivity. The design of 30 m base length cell and the optical scheme are described, the comparison to the known analogous complexes is considered. The results of the study of selective and nonselsective absorption spectra, as well as spectra of gases confined in nanopores are presented.
