Specular reflectance infrared spectra of the macrocycles cyclam and cyclamdione and their Cu( II) complexes deposited onto a smooth copper surface

Abstract

An infrared study of the macrocycles cyclam, cyclamdione and its Cu(II) complexes has been performed. The specular reflectance infrared spectrum was recorded and analyzed for the ligands and complexes deposited onto a smooth copper surface. Several spectral modifications resulting from the macrocycle-metal surface interaction are interpreted in terms of molecular structural changes. An orientation of the ligands and complexes onto the metal surface is proposed. © 1997 Elsevier Science B.V.
