Abstract

Reactions and diffusion of water and oxygen molecules in amorphous SiO2 were studied. In the case of water, vibrational data reveal signatures of both interstitial H2O molecules and silanol groups (SiOH) with the ratios depending on sample preparation, total water uptake and temperature. It is found that molecular H2O is the most stable form of water in a bulk amorphous SiO2.
