The structures formed by hydrogen in two types of silica glass are investigated using infrared spectroscopy, (1)H magic angle spinning magnetic resonance spectroscopy, and quadrupole mass spectrometry. The results obtained from these investigations show that hydrogen in silica glass can exist in the form of isolated SiOH groups, SiOH groups with hydrogen bonds, pairs of neighboring SiOH groups, SiH groups, physically dissolved molecular hydrogen, and molecular water. The structures containing H atoms in the glass synthesized by oxygen-hydrogen gas-flame hydrolysis of SiCl(4) differ from those in the glass produced by melting a silica powder in a hydrogen atmosphere.
