Oxygen-17 Nuclear Magnetic Resonance of Organic Solids

Abstract

We report solid-state ¹⁷O NMR determinations of the oxygen chemical shift (CS) and electric field gradient (EFG) tensors for a series of ¹⁷O-enriched organic compounds containing various functional groups. In several cases, analysis of the n O magic-angle-spinning (MAS) and static NMR spectra yields both the magnitude and relative orientations of the ¹⁷O CS and EFG tensors. We also demonstrate the feasibility of solid-state ¹⁷O NMR as a potentially useful technique for studying molecular structure and hydrogen bonding.
