An O-17-enriched version of the titanosilicate glass, KTS2 (K2O center dot TiO2 center dot 2SiO(2)), was analyzed by O-17 MAS, off-MAS, and 3Q-QCPMG-MAS experiments. Exploiting the variations in EFG and CSA parameters for the O-17 sites in KTS2 glass, we detected four types of oxygen by reduction of spinning sideband intensities in the off-MAS experiments. From the O-17 off-MAS and 3Q-QCPMG-MAS experiments, the Si-O-Ti and K-O-Ti resonances were characterized by a distribution of isotropic chemical shifts, whereas the Si-O-Si resonance was characterized by very small distributions of both EFG tensor and isotropic chemical shift, which means that the disorder in the glass is closely related to Ti. In addition to the order/disorder issue, the most striking feature about the O-17 off-MAS experiments on KTS2 is the lack of signals from Ti-O-Ti, which contradicts linking between corner sharing TiO5 units. Therefore, the structure must consist of linkages between TiO5 units and SiO4 tetrahedra and linkages between SiO4 tetrahedra.
