An analysis of the induced shifts in the nuclear magnetic resonance (NMR) spectra of extractants complexed to paramagnetic lanthanide ions has been performed. The complexes of a number of monofunctional and bifunctional extractants have been examined and assigned solution structures by minimizing the differences between the observed shifts and those calculated using a computer analysis in which the potential configurations of the complexes were generated. Complexes of monofunctional extractants were calculated to have coordination geometries quite similar to those observed in related compounds by crystallographic techniques. For the bifunctional extractants, differentiation between monodentate and bidentate coordination seems possible. 23 references, 2 figures, 7 tables.
