    obtain different energy levels, and become non-degenerate. How these d-orbitals split depend on the geometry of the compound formed, which is the basis of the Crystal Field Theory.2 At certain frequencies of electromagnetic radiation, electrons absorb the energy and get pushed to higher energy orbitals. The frequencies correspond to the energy difference between different orbitals. The energy difference between the non-degenerate d-orbitals correspond to the energy of radiation of the visible…
