## Abstract The observation of long range (10β14 bond) spinβspin coupling between fluorine nuclei (which are very far apart in space) is used to provide information about electronic interactions in bridged dinuclear aromatic compounds.
ALTHOUGH long range spin-spin coupling between benzylic and ring protons (hereafter referred to merely as "benzylic coupling\*) in aromatic compounds has been investigated by a number of workers 1 , there has so far been no attempt to study the variation of this coupling with changes in r electron d
## 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
