Fourier spectroscopy of water vapor in the volume of aerogel nanopores. Part 2. Calculation of broadening and shift of spectral lines by adsorbed molecules

Abstract

The model for simulating the profile of water vapor confined in nanoporous aerogel [2] has been improved. In the improved model, we take into account a possibility of loss of rotational degrees of freedom for water molecules adsorbed on pore walls, collisions with which significantly contribute to line broadening and shifting. The half-widths and shifts calculated for this model are in a good agreement with experimental data.
