Resumen

Chiral amino acids bonded to copperII induce Cotton effects in the visible and UV regions corresponding tod-d and charge transfer transitions 1,2 but and induced Cotton effect on a distant ligand has not been observed to date. We have now observed such an effect effect with mixed complexes of copperII with L- and D-proline pro and 2,2-dipyridyl dip or 1,10-phenanthroline phen, 1 and 2, respectively, in the UV region Fig.1.
