Abstract
The absorption spectra of carbon dioxide confined in aerogel sample with pore sizes of 60 nm have been recorded at a room temperature in the 2250-2400 cm-1 region using a Bruker IFS 125HR FTIR spectrometer. Parameters of spectral lines of CO2 are derived; their dependence on rotational quantum numbers are shown. The results are compared with data available in literature.
