EPR STUDY OF POLYAMINE COPPER COMPLEXES

摘要

A variable temperature EPR study of three polycrystalline poiyamine copper complexes indicates the presence of diverse exchange interactions among the underlying Cu~(2+) ions. Complex EPR spectra are observed indicating the simultaneous presence of molecular and cooperative g-tensors, while appreciable antiferromagnetic interactions become operative at temperatures below approximately 10 K for a part of the Cu~(2+) sublattices.
