When physisorption of H2O occurs on the strongly adsorbed H2O on SrF2, the IR peaks at 3684, 2561, 1947,1656, and 1000 cm-1, which originate from the strongly adsorbed H2O being hydrogen-bonded to the surface F- ion in the form of OH-F-, are widely varied: the consolidation of the peak at 3684 cm-1 into a broad band centered at 3400 cm-1, the shift of the peak at 2561 cm-1 to 2980 cm-1, the disappearance of the peak at 1947 cm-1, the appearance of the peak at 2280 cm-1, an increase in the intensity of the peak at 1656 cm-1, and a gradual shift of the peak at 1000 cm-1 to 880 cm-1. Most of these phenomena were interpreted in terms of the physisorption of H2O on top of the surface F- ion, which results in a weakening of the hydrogen bonding of the preadsorbed H2O. An additional effect comes from the physisorbed H2O itself.
