Optical activity of nickel(II) and copper(II) complexes with L-aminoacids in the UV spectral region (Elsevier Sequoia, 1972)Complexes of Cu(II) and Ni(II) with L-aminoacids have been prepared and their UV spectra and optical activity studied. The results are interpreted in terms of the conformation of the chelated rings. A molecular orbital ...
