Question

What is crystal field splitting energy? Draw a figure to show spitting of degenerate orbitals in an octahedral crystal field?

Answer 1

Crystal field stabilization energy:

It is the energy of $e^{-}$ configuration in the ligand field minus the energy of the $e^{-}$ configuration in isotropic field.

$CFSE=△E=E_{ligandfield}-E_{isotropicfield}$

$CFSE$ depends on-

• Geometry that changes the d-orbital splitting pattern.
  
• Number of d-$e^{-}s$
  
• Spin Pairing energy
  
• Ligand character via spectrochemical series.
