Solvent effect on metal

Solvent effects on metal resonances are routinely tens of ppm, and changes in temperature during a measurement result in large enough shifts (often in the range 0.1-0.5 ppm °C ) that fine structure on the resonance is readily lost. Isotope effects (e.g., Cl vs. Cl, vs. 0, or vs. H) on metal resonance positions " are sufficiently large that the different chemical shifts from the individual isotopomers are often well resolved. These effects are not so marked in donor-atom NMR spectra, i.e., for N, or P complexed to a metal center, solvent effects are normally a few ppm or less.
