Studies of organophosphorus selenides by heteronuclear magnetic triple resonance

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.
