    Abstract

    Broadening and shifting of absorption lines of water vapor confined inside aerogel nanopores have been studied with the help of a IFS 125 HR Fourier spectrometer in the region 5000–5600 cm−1. It is shown that strong spatial limitation of molecular movement results in significant broadening and shifting of spectral lines. A semiempirical model for description of the form of absorption line contours for H2O molecules confined inside aerogel nanopores, taking account of the dependence of spectral line half-width on rotational quantum numbers, is presented for the first time. Values of spectral line half-widths found experimentally and theoretically are in good agreement.
