title: One- and two-dimensional 1H magic-angle spinning experiments on hydrous silicate glasses.
abstract: Applications of various one- and two-dimensional 1H magic-angle spinning nuclear magnetic resonance (MAS NMR) techniques for the elucidation of structural properties of hydrous silicate glasses are described. Advantages and limitations of one-dimensional experiments [MAS and combined rotation and multiple-puls spectroscopy (CRAMPS)] and of two-dimensional approaches (spin-exchange experiments, "MAS-CRAMPS" correlation plus extended versions) are discussed. The various 1H MAS NMR techniques are illustrated by practical examples of spectra obtained from a hydrous silicate glass of Na2O.4SiO2.0.7H2O composition.
