Rotational dependence of line half-windth for fundamental band of CO<sub>2</sub> confined in nanoporous aerogel
The absorption spectrum of carbon dioxide confined in aerogel have been measured in the 2250-2400 cm<sup>-</sup><sup>1</sup> region for the first time using a Bruker IFS 125HR FTIR spectrometer. Dependence of CO<sub>2</sub> half-widths on rotational quantum numbers was studied and compared with the data available in literature.
