摘要：

Applications of various one- and two-dimensional H-1 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 H-1 MAS NMR techniques are illustrated by practical examples of spectra obtained from a hydrous silicate glass of Na2O . 4SiO(2) . 0.7H(2)O composition.
