In this paper Lanthanide-induced shifts have been measured for ¹³C and ¹H nuclei of glycyl-glycine,glycyl-DL-valine and glycyl-L-leucine in the presence of lanthanide cations (La³⁺,Ho³⁺ and Yb³⁺) in aqueous solution.The simulation to conformations of lanthanide dipeptide complexes shows that the ligands are coordinated to lanthanide ions through oxygen donors of carboxyl groups.In the complexes dipeptides are in extended state.
