Proton and 13 C NMR parameters have been determined for phenyldibenzophosphole and its oxide, sulfide, selenide and W(CO) 5 complex from high‐resolution one‐ and two‐dimensional (COSY, HETCOR and 2DJ) experiments at 4.7, 7.1 and 9.4 tesla. Assignments of chemical shifts and coupling constants have been made and verified by computer simulation of the proton spectra. The data are discussed in relation to the geometry and electron density at phosphorus and the diamagnetic anisotropy of the W(CO) 5 group.
