## Abstract Threeβdimensional NMR imaging was used to create true maps of the ^14^N distribution in aqueous phantoms containing ammonium nitrate and sodium azide. The technique allowed for the creation of separate images from each nitrogen chemical environment and a total nitrogen image devoid of a

A characterisation by 14N NMR of the binary nitrides AlN and BN is presented. Both the static and magic angle spinning (MAS) lineshapes have been investigated in order to determine, or set upper limits on, the nuclear quadrupole coupling (Cq) at the nitrogen site. Additional data are given for the C
## Abstract Directly detected ammine ^14^N NMR chemical shifts of 20 amminecobalt(III) compounds are reported. The coordination shifts, Ξ΄~CS~ = Ξ΄~coord~ β Ξ΄~free~, are in all cases negative and range from β4.4 ppm for the __trans__ ammine ligand in [Co(NH~3~)~5~(CH~3~)]^2+^ to β73.6 ppm for the tra
