Paper Abstract

IR absorption spectra of high-purity silica glass (SiO2) containing from 0.1 to 103 ppm of hydroxyl (OH) groups were studied and quantum-chemical calculation of OH groups embedded in different ways in the silica glass network was performed. On this basis a new approach to the problem of OH groups embedding in the glass network is proposed: hydroxyl occurs in high-purity SiO2 mainly as single groups rather than paired groups and some of them are hydrogen- bonded to bridging oxygen atoms, and not only to each other, as it is considered now. New decomposition of the fundamental OH stretching vibrational band into components was proposed.
