Shift References in High-Resolution Solid-State NMR

Abstract

The high-resolution solid-state 13C, 29Si, 31P, 23Na, 27Al, and 11B NMR spectra of several compounds have been measured using magic-angle sample spinning. Their isotropic chemical-shift values have been determined accurately to use as shift references in solid-state NMR; this makes comparison between literature shift data possible.
