States of Matter & Gas LawsCrystal Defect
Any irregularity that interrupts the perfectly ordered arrangement of particles in a crystal.
Inorganic & Coordination ChemistryCrystal Field Splitting Energy
The energy difference between the sets of d orbitals produced when a ligand field lifts their degeneracy.
Inorganic & Coordination ChemistryCrystal Field Stabilisation Energy
The net energy gained by a complex through the preferential occupation of lower-energy d orbitals.
