Molybdenum-95 and tungsten-183 n.m.r. spectra have been measured by direct observation and by multiple-resonance methods respectively for 65 related derivatives of and with (mainly) phosphorus ligands.The chemical shifts of the two nuclei are remarkably parallel, those for (183)W being ca. 1.7 times more sensitive to changes in chemical environment than those for (95)Mo.The chemical shifts are temperature-dependent, and trends in them can be largely accounted for by variations in the mean electronic excitation energy.The metal-phosphorus spin-coupling constants are very predictable.Molybdenum-95 linewidths in many cases are quite small, and can be broadly explained by the use of a point-charge model.
