Abstract

A heteronuclear magnetic selective triple resonance technique for the determination of chemical shifts in incomplete spin systems is described and applied to the measurement of ⁷⁷Se chemical shifts in organophosphorus selenides. The results indicate that the dipolar form makes a major contribution to the phosphorus–selenium bond, but π-bonding between phosphorus and selenium is also important. The ³¹P–⁷⁷Se spin coupling constants are negative and can be interpreted in terms of the inductive effect of the substituents of the phosphorus atom.
