2 D "P, "N heteronuclear shift correlation, based on a non-refocused INEPT pulse sequence with "N detection, was applied to a "N NMR study of the azadiphosphiridines 1-5 which are formed by (2 + 11 cycloaddition of iminophosphines, RP=NR'.

A 31 P and 15 N NMR study of cyclotriphosphazenes 1-4 and preparation of polyphosphazenes, and the properties of these polyphosphazene 5 has been carried out including solvent and materials can be tuned by the incorporation of different substitusubstituent effects. 15 N chemical shifts and 31 P, 15
31P and 15N NMR spectra of 11 cyclic and non-cyclic phosphoramidates were measured. Comparison of the closely related structures demonstrated correlation between the bond angles at nitrogen and the 15N NMR chemical shifts and the 1J(P,N) coupling constants. 15N NMR parameters allowed the exo-and end
