Bunel Torrealba, Sergio; Ibarra, Carmen; Urbina, A.; Bunton, Clifford A. (Pergamon Press, 1977)Chiral amino acids bonded to copper(II) 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 ...

Bunel Torrealba, Sergio; Ibarra, Carmen; Rodríguez, M.; Urbina, A.; Bunton, Clifford A. (Pergamon Press Ltd., 1981)Mixed 1:1:1 complexes of proline or aspartic acid with Cu(II) and 9:10-phenanthroline (phen) or 2,2'bipyridine (bipy) show induced Cotton effects in the aromatic region. The effect is ascribed to interactionsbetween the ...

Bunel Torrealba, Sergio; Ibarra, Carmen; Rodríguez, M.; Urbina, A.; Bunton, Clifford A. (Pergamon Press, 1981)Complexes of Cu(II) with L-aminoacids have positive charge transfer bands in their CD spectra at ca.230 nm and negative at ca. 270 nm. Examination of complexes with L-1,2-diamino propane shows that the positive band is ...
