ABSTRACTGlasses in the Al2O3-B2O3-Fe2O3-Na2O-SiO2 system were produced at a temperature of 1150 °C, poured onto a metal plate and annealed. The nature of the structural units and their bonding in the structure were studied by infrared and Raman spectroscopic techniques. The structural network of all the glasses studied is built from major [SiO4] tetrahedra with 2-3 non-bridging oxygens (NBO). Incorporation of Fe2O3 offers a destructive effect in the glass network.

Homogeneous glasses were formed in the Cr 2 O 3- TeO 2- B 2 O 3- SrF 2 system, up to 20 mol% Cr 2 O 3. For these glasses, IR and Raman spectral measurements were carried out in order to elucidate the local structure. The results showed that BO 3 and BO 4 are the main structural units of the glass system and the chromium ions are located in the network. It was evidenced the presence of TeO 3 and TeO 4 units as possible structural units in our glasses.

The work outlines general ideas on how the frequency and the intensity of proton vibrations of X–H×××Y hydrogen bonding are formed as the bond evolves from weak to maximally strong bonding. For this purpose, the Raman spectra of different chemical compounds with moderate, strong, and extremely strong hydrogen bonds were obtained in the temperature region of 5 K–300 K. The dependence of the proton vibrational frequency is schematically presented as a function of the rigidity of O-H×××O bonding. The problems of proton dynamics on tautomeric O–H···O bonds are considered. A brief description of the N–H···O and C–H···Y hydrogen bonds is given.
