Three-dimensional lattice connectivities from two-dimensional high-resolution solid-state NMR. 29Si MAS NMR investigation of the silicate lattice of zeolite ZSM-39 (Dodecasil 3C)

Description

The potential of 2D 29Si high-resolution solid-state NMR spectroscopy to establish three-dimensional Si OE Si lattice connectivities in zeolites has been investigated using a 29Si-enriched sample of zeolite ZSM-39. Spin-diffusion measurements reveal the correct connectivities for the (known) structure, but further work on other systems will be needed to establish the reliability of these measurements due to possible contributions from non-distance-dependent factors. 29Si COSY experiments also yield the correct connectivities and are unambiguous in this regard as they depend only on scalar (through-bond) couplings and thus greatly extend the potential of high-resolution solid-state NMR in the investigation of lattice structures
