18. In these experiments, the ratio (histidine]/[Cu(II)] was 2.0, to ensure that the axial coordination sites of Cu(II) are free. Under these experimental conditions, more than 99% of the Cu(II) is present as bis(histidine)copper(II).
19. Since ionic strength can affect the spectral features, it was kept constant by suitable addition of NaCl.
