Rapid solid-state 29Si NMR chemical shift refinements of pure silica zeolite frameworks with an improved structure-to-shift correlation

The chemical shifts measured in solid-state 29Si NMR spectroscopy of pure silica zeolites are highly sensitive to the local geometry surrounding the corresponding silicon atoms and therefore hold promise for playing an important role in the structure determination of zeolite frameworks. Through an analysis of the large set of experimental 29Si NMR spectra of pure silica zeolites available in the Database of Zeolite Structures, including the …
