NMR active nuclei of the group 15 elements

    Nuclei that are NMR active are listed in Table 1.1.     Routinely, ³¹P NMR spectroscopy is used in characterizing P-containing species. Chemical shifts are usually reported with respect to δ = 0 for 85% aqueous H₃PO₄, but other reference compounds are used, e.g. trimethylphosphite, P(OMe)₃. The chemical shift range for ³¹P is large.
