17O lanthanide-induced paramagnetic shifts are reported for nine different lanthanide ion-proline complexes in aqueous solution at pH 3. The results indicate that the hyperfine coupling constant for the directly liganded proline and water oxygens is indeed invariant for the nine lanthanide cations examined. This suggests that previous breaks in data for lanthanide-induced shifts along the lanthanide cation series must arise from changes in the non-axial dipolar contributions to these shifts near the center of the series.
