2 Visible Spectra of Transition- Metal Complexes Color in transition-metal complexes   is explained as due to a jump of an  electron from the lower-energy to the  higher-energy d orbitals. The crystal field splitting can be obtained experimentally from the visible spectrum of a complex. Note that the energy change when light is absorbed equals the crystal field splitting, .
