Phosphorus-31 CP/MAS NMR spectra of two linear bis(tribenzylphosphine)cuprate(I) salts reveal significant anisotropy in the one-bond 31 P, 63,65 Cu J tensors. The parallel and perpendicular components of 1 J( 31 P, 63 Cu), for example, are Ψ‰2.0 and Ψ‰1.3 kHz, respectively. The well-characterized spac

Inner projections of the polarization propagator (IPPP) are used to study several features of the throughspace transmission of 31P-31P coupling constants. Cis-l,2-diphosphinoethylene is chosen as a model compound. INDO ground state wave functions are used, including two different second-row paramete

Several scalar coupling constants (mainly 31P, 31P) were calculated for 10 cyclotriphosphazenes and compared with experimental results when available. Although the experimental values cannot be reproduced, the calculated values are proportional to the experimental values. Some difficult cases, such

## Abstract Several Ξ±,β‐diphosphonates with a norbornane or cyclohexane skeleton were prepared, and the ^31^P‐^31^P coupling constants over three bonds for the ethyl or methyl esters, the acid and anion were obtained from the ^13^C NMR spectra or the ^13^C satellites in the ^31^P NMR spectra. The ^
