Abstract

Infrared absorption spectra were measured to make clear the adsorbed state of strongly adsorbed H₂O on SrF₂. The IR spectra of the strongly adsorbed H₂O involve three absorption peaks at 2561, 1947, and 1000 cm^-1, which did not appear on metal oxides, besides the peaks characteristic of H₂O adsorbed on the latter substances. These three peaks can be elucidated to originate from molecularly adsorbed H₂O on the (100) plane of SrF₂, the molecule being located at the F^- ion-vacant site and hydrogen-bonded to the neighboring F^- ion. A model for the H₂O molecule adsorbed at the special site on SrF₂ is postulated.
