## Abstract The coupling constants ^n^__J__(^77^Se^31^P), __n__ = 1β4, have been measured in the protonβdecoupled ^31^P NMR spectra of a range of diphosphorus selenides and diselenides. ^31^Pβ{^1^H, ^31^P} and ^31^Pβ{^1^H, ^77^Se} triple resonance experiments have been used to establish the signs o
