Optical properties in different solvents of gramicidin‐bis (salicylaldimine) Cu(II) and (5‐I‐salicyladimine) Cu(II) chelates are intercepted in terms of their molecular structure. A molecular model for the inversion of Contton effects in two different classes of solvents is proposed. This explanation is supported by the study of optical properties of model compounds.
