Even without expensive isotope enrichment, it is possible to obtain nitrogen NMR parameters in the solid state. The isotropic chemical shifts in hexagonal and cubic boron nitride, and for the hexagonal modification also the quadrupole coupling, can thus be obtained for the first time. The recorded 14 N MAS NMR spectrum (28.809 MHz) of hexagonal boron nitride is shown on the right.
