Fourier Transform Spectroscopy of CO and CO2 Confined in Aerogel Nanopores in the Near-IR Range

The 3–0 absorption band of carbon monoxide and the 2 0 0 13–0 0 0 01 band of carbon dioxide confined in aerogel were recorded using a Bruker IFS 125HR FTIR spectrometer. The parameters of spectral lines are determined; their dependences on rotational quantum numbers are derived. The parameters we found are compared with those for the 2–0 band of carbon monoxide and the 0 0 0 11–0 0 0 01 band of carbon dioxide taken from the literature.
