What is crystal field stabilization energy (CFSE)?
उत्तर
The crystal field stabilisation energy is defined as the energy difference of electronic configurations in the ligand field (ELF) and the isotropic field (Eiso).
CFSE (ΔE0) = (ELF) – (Eiso)
= (nt2g (−0.4) + neg (0.6) Δ0 – npP) – (n’pP)
Here ntg is the number of electrons in t-orbitals
neg is the number of electrons in e-orbitals
np is the number of electrons in the ligand field
n’p is the number of electrons in the isotropic field
