摘要
The paramagnetic chemical shifts in the H-1 and C-13 NMR spectra of lanthanide complexes (Ln = Eu, Yb, and Pr) with diethylenetriaminepentaacetic acid were analyzed. It was demonstrated that Eu+3 in aqueous solution can coordinate to one of the carboxylate groups in a chelating bidendate fashion through two O atoms.
