Abstract

Vacuum-ultraviolet (VUV) absorption cross sections of hydrogenated and deuterated silanol groups (SiOX, where X=H or D) as well as interstitial water molecules (X2O) in amorphous SiO2 (aSiO2) were determined between photon energies of 7 and 8.2eV. The absorption bands for the deuterated species are blueshifted compared to those for the hydrogenated ones by 0.1to0.2eV as a result of a decrease in the zero-point energy associated with the OX groups. The VUV absorption of interstitial X2O below 8eV is blueshifted with respect to that of X2O trapped in rare-gas solids due to the contribution of hydrogen bonding, and is 1 to 2 orders of magnitude stronger than that of SiOX groups.
