    Abstract

    The bonding state of OH groups in silica glasses is studied by examining infrared absorption spectra and thermal annealing characteristics of γ-induced paramagnetic detect centers. When an oxygen-rich silica is treated by hydrogen, OH groups exist in the form of those hydrogen-bonded with nonbridging oxygen (≡Si-O- - - -H-O-Si≡) besides the forms of H2O and ≡Si-O-H.
