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.

CFSE Calculator

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.
