Applications of Dipolar NMR Spectroscopy in Characterizing Nitrogen and Phosphorus Shielding Tensors

Abstract

The application of dipolar NMR techniques to the characterization of nitrogen and phosphorus shielding tensors is discussed. After a brief outline of the theoretical basis of the technique, results from the authors’ laboratory are presented. Nitrogen shielding tensors in several compounds containing two-coordinate nitrogen functional groups are characterized and compared to those calculated for related model compounds using the localized orbital-local origin (LORG) method.
