A study of the layered alkali metal silicate, magadiite, by one- and two-dimensional 1H and 29Si NMR spectroscopy
Abstract
The layered alkali metals silicate magadiite is analysed by solid-state MAS/NMR techniques, showing that there is strong hydrogen bonding(but not in sodium-free forms) and that the hydrogen-bonded proton is the principal source of cross-polarisation for all types of silicon.
