The difference between d-d transition and charge transfer (CT) transition are as follows In the d-d transition, the transition occurs

In [Ti(H2O)6)]3+, Ti3+ ion has only one electron in 3d-orbital. The electron occupies the orbital of the lowest energy, i.e.,

In high spin octahedral d5 complexes like [Mn(H2O)6]2+, Mn2+ ion has five unpaired electrons which are filled parallelly in all

The reason for the colour of potassium dichromate (K2Cr2O7) is ligand to metal charge transfer (LMCT) transition. In Cr2O72-, Cr

The crystal field splitting in octahedral complexes (Δo) is double than that in tetrahedral complexes (Δt) (i.e., Δo is double

Tetrahedral complexes are high spin because (i) Δt = 4/9 Δo, i.e., tetrahedral crystal field splitting is half the crystal

The postulates of crystal field theory are Ionic ligands such as Cl–, OH–, CN– are regarded as negative point charges
