Chiroptical properties and absolute configuration have been correlated for a series of [Ln(oda) 3 ] 3− complexes in aqueous solution (Ln=Pr, Nd, Sm, Eu, Tb, Dy, Ho, Er, or Tm; oda=2,2′‐oxydiacetic acid). Addition of the chiral probe L ‐proline ( L ‐Pro) to a series of the racemic complexes resulted in an excess of the Λ‐enantiomer.
