Abstract
The influence of sintering of an aerogel sample on spectral lines parameters of the carbon monoxide confined inside its pores was studied for the first time. The measurements were conducted using в Bruker IFS 125HR spectrometer in the 4000-4400 cm-1 spectral region. It was shown that the sintering increased CO half-widths but did not affected rotational dependences of CO lines.
