    OD bands in the IR spectra of a deuterated soda-lime-silica glass
    (Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 2001) Peuker, Christel; Brzezinka, Klaus-Werner; Gaber, Martin; Kohl, Anka; Geißler, Heinz
    IR spectra of a deuterated glass of the composition (in mol%) 16 Na2O · 10 CaO · 74 SiO2 complete earlier spectroscopic studies on water-poor soda-lime-silica glasses. The approved IR spectroscopic method of the deuterium exchange allows a reliable assignment of the hydroxyl bands also in the case of glasses. By spectra comparison the assignment of the IR bands at 3500 and 2800 cm-1 to hydroxyl groups with different hydrogen bonding is verified. The IR band at about 4500 cm-1 is interpreted as both a combination of the stretching vibrations vO-H and vSi-OH and a combination of the stretching vibration vO-H and the deformation vibration δSiOH. The bands at 1763 and 1602 cm-1 are attributed to combination vibrations of the glass network.
