Abstract

A convenient, sensitive, and accurate nuclear magnetic double resonance technique is described for the determination of J(XX′) in A_nA′_nXX′ spin systems in which J(AA′) is zero and |J(XX′)| is large compared with |J(AX)–J(AX′)|. The method is applied to the determination of the sign and magnitude of J(PP) in trans-{(MeO)(PhO)₂P}₂Mo(CO)₄, trans-{(Me₂N)₃P}₂PtCl₂, {(MeO)₂P(O)}₂Hg, MePhP･PMePh, and trans-(Et₃P)₂[Me₂N(C:)H]RhCl₃.
