Abstract

In this paper, we estimate the type of orientation of H₂O molecules adsorbed on the surface of airgel nanopores based on experimental data on the broadening of the vibrational-rotational lines of the H₂O molecule during its collisions with H₂O molecules on the surface of the airgel in their chaotic and ordered orientation. It is shown that the experimental data are consistent with the model of orderly oriented H₂O molecules on the surface of SiO₂ nanopores.
