Oxygen-17 Nuclear Magnetic Resonance Study of the Structure of Mixed Cation Calcium−Sodium Silicate Glasses at High Pressure: Implications for Molecular Link to Element Partitioning between Silicate Liquids and Crystals

The structure of silicate glasses and the corresponding liquids at high pressure and their structure-property relations remain difficult questions in modern physical chemistry, geochemistry, and condensed matter physics. Here we report high- resolution solid-state O-17 3QMAS NMR spectra for mixed cation Ca-Na silicate glasses quenched from melts at high pressure up to 8 GPa. The spectra provide the experimental evidence for the varying pressure-dependence in two different types of nonbridging oxygen (NBO) environments (i.e., Na-O-Si and mixed (Ca,Na)-O-Si) in the single glass composition. The percentage of NBO drops significantly with increasing pressure and is a complex function of melt composition, including cation field strength of network modifying cations. A decrease in NBO fraction with pressure is negatively correlated with the element partitioning coefficient between crystals and liquids at high pressure.

High-field vanadium-51 and oxygen-17 nuclear magnetic resonance study of peroxovanadates(V)

High-field 51V and 17O n.m.r. spectroscopy has clarified the aqueous chemistry of the peroxovanadates, leading to the identification of five new species, four of which are dimeric, Mono- and di-peroxovanadates undergo a change of co-ordination from octahedral to tetrahedral when their final proton is removed.

Vanadium-51 and oxygen-17 nuclear magnetic resonance study of vanadate(V) equilibria and kinetics

Approximately 15 vanadate(V) and polyvanadate(V) species have been identified by 51V n.m.r. in the range pH 7–14, mostly for the first time. Oxygen-17 n.m.r. spectroscopy confirms in several cases that the vanadium coordination is tetrahedral, and that the 17O shifts are correlated closely with formal π-bond order. Most linear and cyclic catenations of VO4 tetrahedra are found up to V6, but there is no branched or triprotonated species or cyclic trimer. Several equilibrium constants and pKa values are reliably measurable. The ion [HVO4]2– rather than OH– is shown to be the dominant nucleophile in the two main ring-breaking reactions, and a simple kinetic pathway is proposed for the formation of decavanadate ion.
