Crystal Field Splitting Energy
Crystal Field Stabilization Energy
The energy difference between the Bary center and the lowest splitted d-orbitals is called Crystal Field Splitting Energy or Crystal Field Stabilization Energy (CFSE). In other words, the amount of energy by which a complex is stabilized in crystal field is called CFSE. Greater the CFSE, greater the stability of the complex.

Example- Calculation of CFSE of d4 Low Spin and d4 High Spin Complexes.

CFSE of d4 Low Spin complex is more than that of d4 High Spin. So, d4 Low Spin is more stable complex.
