WebExplain Crystal Field Theory. CFT Crystal field theory is based upon orbitals but does not go fully into all of the molecular orbitals and potential combinations etc. (That is called Ligand Field Theory–vide supra) With CFT we are just going to consider the d-orbitals and how they can interact with ligands o d-orbitals are highly directional WebMar 24, 2024 · From the point of view of crystal field theory, it means that the crystal field splitting energy increases. This is only because the ligands are assumed to only donate electron density. That is, the t2g orbitals can apparently never get any lower in energy than the free-ion d orbital energies (which isn't true in real life). IMPORTANT NOTE: spurt industries wixom mi
