WebAug 14, 2024 · Crystal field theory represents a semi-empirical approach to describe localized states in an atomic or crystallographic surrounding. The crystallographic surrounding or crystal field is described in terms of a small perturbation Vcr(→r) leading to the total Hamiltonian [- ℏ2 2m ∇ 2 + V(→r) + Vcr(→r)]ψ(→r) = Eψ(→r). (2) WebIn terms of d-orbital splitting, ligand field theory (LFT) and crystal field theory (CFT) give similar results. CFT is an older, simpler model that treats ligands as point charges. LFT is more chemical, emphasizes covalent bonding and accommodates pi-bonding explicitly. High-spin and low-spin systems [ edit]
