Assuming the Dq parameter as a key quantity (for a given symmetry and applying the CIELAB (or CIELUV)) colour coordinates, characteristic curves of colour travel were simulated and experimentally supported for Cr(II), Cu(II), VO(II) and Fe(II) complexes. Preliminary data were also obtained...
ConceptualTransition metals usually from coloured complexes and d-d transitions (t(2g)hArre(g)) are responsible for colour as the energy difference between t(2g) and e(g) lies in visible region. But all the coloured ions are not dut to d-d transition but
