Crystal Field Theory
Crystal Field Theory (Text : JD Lee; pp 204-222) This theory ( CFT) largely replaced VB Theory for interpreting the chemistry of coordination compounds It was proposed by the physicist Hans Bethe in 1929 Subsequent modifications were proposed by J H Van Vleck in 1935 to allow for some covalency in the interactions |
What does CFT stand for?
Crystal Field Theory (CFT). Crystal Field Theory (CFT), An Introduction. Lecture 3. CHEM1902 (C 10K) Coordination Chemistry In the ionic CFT, it is assumed that the ions are simple point charges. When applied to alkali metal ions containing a symmetric sphere of charge, calculations of bond energies are generally quite successful.
How can CFT be used in a tetrahedal crystal field?
The CFT approach can be easily extended to other geometries and the next most important case is the tetrahedron . To predict the splitting pattern of the energy of the d-orbitals under a tetrahedal crystal field you may once again find it convenient to consider how the ligands can fit into a cube to give a tetrahedron .
What is ligand field theory (CFT)?
CFT was developed by physicists Hans Bethe and John Hasbrouck van Vleck in the 1930s. CFT was subsequently combined with molecular orbital theory to form the more realistic and complex ligand field theory (LFT), which delivers insight into the process of chemical bonding in transition metal complexes.
Does CFT explain bonding in transition metal complexes?
This theory has been used to describe various spectroscopies of transition metal coordination complexes, in particular optical spectra (colors). CFT successfully accounts for some magnetic properties, colors, hydration enthalpies, and spinel structures of transition metal complexes, but it does not attempt to describe bonding.
