WebCrystal Field Theory explains colors of Coordination compounds as follows : A d-orbital splits into multiple orbitals, the process being called crystal field splitting. When white light falls on the compound, an electron makes a transition into a higher state thus absorbing a particular wavelength of light. The rest of the light is reflected. WebSep 16, 2024 · The energy absorbed by the electron to jump corresponds to the crystal field splitting, so, the greater the energy difference, the higher energy colors would be absorbed.
