Abstract
The absorption spectrum of carbon dioxide confined in aerogel have been measured in the 2250-2400 cm-1 region for the first time using a Bruker IFS 125HR FTIR spectrometer. Dependence of CO2 half-widths on rotational quantum numbers was studied and compared with the data available in literature.
