The model for simulating the profile of water vapor confined in nanoporous aerogel  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.
