- They can be uploaded on commons and reused in crystal field theory.
- The agreement of the hydration enthalpies with predictions provided one basis for the general acceptance of crystal field theory.
- The energy gap separating these two sets is the basis of crystal field theory and the more comprehensive ligand field theory.
- Interactions of electrostatic potential with many-electron states of atoms / ions are most commonly described in crystal field theory.
- The rationale for why the spin states exist according to ligand field theory is essentially the same as the crystal field theory explanation.
- Similar ion-like 3d4s configurations occur in transition metal complexes as described by the simple crystal field theory, even if the metal has oxidation state 0.
- J . H . Van Vleck established the fundamentals of the quantum mechanical theory of magnetism and the crystal field theory ( chemical bonding in metal complexes ).
- In crystal field theory, " d "-" d " transitions that are spin-forbidden are much weaker than spin-allowed transitions.
- For example, Cu II 2 ( OAc ) 4 ( H 2 O ) 2 is almost diamagnetic below room temperature whereas Crystal Field Theory predicts that the molecule would have two unpaired electrons.
- This was an important factor contributing to the acceptance of crystal field theory, the first theory to successfully account for the thermodynamic, spectroscopic and magnetic properties of complexes of the transition metal ions and precursor to ligand field theory.
- Crystal field theory describes a number of physical phenomena well but does not describe bonding nor offer an explanation for why " n " s electrons are ionized before ( " n " " 1 ) d electrons.
- Crystal field theory may be used to explain the relative stabilities of transition metal compounds of different coordination geometry, as well as the presence or absence of paramagnetism, whereas VSEPR may be used for complexes of main group element to predict geometry.
- Taube felt that a " primary flaw " with his correlation between electron configuration and ligand substitution was that it was described mainly in terms of valence bond theory, as crystal field theory and ligand field theory were not well established when he published his work in 1952.
- However, keep in mind that " the spectrochemical series is essentially backwards from what it should be for a reasonable prediction based on the assumptions of crystal field theory . " This deviation from crystal field theory highlights the weakness of crystal field theory's assumption of purely ionic bonds between metal and ligand.
