Abstract

The experiment on water molecule adsorption on the surface of nanoporous polymeric adsorbent in the Knudsenmode under conditions of selective action of IR radiation is described. Resonant excitation of the vibrational-rotational transition of the ortho-modification of H2O molecules at a wavelength of 1.85 µm is used. The applicability of this method to the production of water vapor with nonequilibrium concentration ratios of ortho and para modifications of water molecules is shown.
