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.enghttps://creativecommons.org/licenses/by/3.0/de/660Article
