Abstract:

Calculations of line broadening and line shift of water vapor and carbon oxide confined in nanoporous media are presented. The collisions of free H2O (CO) molecules with physically adsorbed on the surface molecules are discussed. Changes in the rotational structure of levels in physically adsorbed molecules are taken into account. The comparison with the existing experimental data is performed.

Keywords:

water vapor, carbon oxide, nanopores, halfwidth and shift of spectral lines
