CRYSTRAL FIELD THEORY
Assumptions-
1. Ligand- Negative point charges and Neutral point dipole
2. Meta- ligand bonding- Purely electrostatics in nature
Strong Field ligand (low spin) : Large splitting of –orbitals
Weak Field ligand (High spin) : Small splitting of –orbitals

Example- [Ti (H2O)6 ]3+
CFSE of Octahedral Complexes
Formula-
CFSE = -0.4 x T2g + 0.6 X Eg x Δo
