It is the energy difference between lower energy and higher energy d-orbitals after splitting of d-orbitals

(i) Δ0 > P
t4 2g eg0

(ii) Δ0 < P
t3 2g eg1

In an octahedral complex, the d orbitals of the central metal ion divide into two sets of different energies. The separation in energy is the crystal field splitting energy, Δ. (A) When Δ is large, it is energetically more favourable for electrons to occupy the lower set of orbitals.
