Abstract

The vibrational spectra of silicate glasses provide some clues on the structure and stability of the glass-forming network. Wavenumbers of Raman bands are related to the types of linkages within the network and Raman intensities to the “speciation” within the network. Absolute infrared intensities which can be obtained from deconvolution of specular reflectance spectra can be used to obtain dipole derivatives which in turn can be correlated with effective charges on bridging and non-bridging oxygens. IR and Raman spectra measured on a variety of silicate glasses are used to extract network polymerization and bond effective charges which in turn are related to the durability of the glasses.
