ESR and optical absorption studies on the copper (II) interaction with aromatic amino acids.

L Sportelli, H Neubacher, W Lohmann.   

Abstract

Electron spin resonance and optical absorption studies have been done in order to investigate the interaction between Cu2+ and aromatic amino acids in aqueous solution at 77 K and at room temperature as well. Depending on the concentration each aromatic amino acid can form two different kinds of complexes with Cu2+ which can be characterized by its ESR pattern. Additional information was obtained from optical d-d and CT transitions.
