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.
