Far Infrared Spectra of Bis(Aminoacidato) Copper(II) Complexes: Assignment of Copper Ligand Vibrations by Isotopic Substitution

Abstract
Application of isotopic substitution with 65Cu to the study of the far infrared spectra of Bis(L-aminoacidato)copper(II) complexes reveals that metal sensitive vibrations lie at ca. 380 and ca. 330 cm−1. They are tentatively assigned as ν(Cu-N) and ν(Cu-O) respectively.
