| Abstract: | Infrared spectra of H+(H2O)nβ″ alumina show than the dehydrated samples contain H3O+ ions as dominant species while the hydrated ones consists mainly of H3O+ and H5O+2 entities. Oxonium ions can occupy many different positions more or less distant form the ideal prismatic sites. This structural disorder in the conductivity plane is believed to be the main factor responsible for the high conductivity of the material. |
