Popis:	Bis(diphenylphosphanyl)amine (1), the disulfide 1S and diselenide 1Se were selected to show the efficient application of the INEPT-HEED pulse sequence for measuring coupling constants 1J(31P.15N) and isotope induced chemical shifts1⊿14/15N(31P), both at natural abundance of 15N, from 31P NMR spectra. The sign of 1J(31P,15N) (> 0) in all three compounds was determined by selective heteronuclear ]1H{31P} double resonance experiments.
