✦ Synopsis

The isotope-induced chemical shifts 1 14/15 N( 31 P) were determined at natural abundance of 15 N by using HEED INEPT experiments. A dependence of 1 14/15 N( 31 P) on the substituents at nitrogen was found (alkyl < H < aryl; increasingly negative values). The magnitude and sign of the coupling constants 1 J( 31 P, 15 N) (positive sign
