In molecular physics, crystal field theory (CFT) describes the breaking of degeneracies of electron orbital states, usually d or f orbitals, due to a static electric field produced by a surrounding charge distribution (anion neighbors).

A conformal field theory (CFT) is a quantum field theory that is invariant under conformal transformations. In two dimensions, there is an infinite-dimensional algebra of local conformal transformations, and conformal field theories can sometimes be exactly solved or classified.

晶体场理论（英語： Crystal Field Theory CFT）是一种配位化学理论。 它以 过渡金属 配合物 的电子层结构为出发点，可以很好地解释配合物的 磁性 、颜色、立体构型、热力学性质和配合物畸变等主要问题，但不能合理解释 配体 的 光谱化学序列 和一些金属有机 ...

2023年6月30日 · Crystal field theory (CFT) describes the breaking of orbital degeneracy in transition metal complexes due to the presence of ligands. CFT qualitatively describes the strength of the metal-ligand bonds.

Crystal Field Theory (CFT), introduced in the early 20th century by Hans Bethe and later developed by J. H. Van Vleck and Linus Pauling, revolutionized the understanding of transition metal complexes. CFT focuses on the interaction between the d-orbitals of the central metal ion and the ligand field generated by surrounding ligands.

Crystal field theory (CFT) describes the breaking of degeneracies of electron orbital states, typically d or f orbitals, caused by a static electric field generated by a surrounding charge distribution (anion neighbours).

2021年12月29日 · H. Bethe and V. Bleck proposed the crystal field theory (CFT). This theory describes metal complexes’ bonding, characteristics, electronic spectra, and magnetism in greater detail. Crystal field splitting is the conversion of five degenerate d-orbitals of a metal ion into different sets of orbitals with varying energies in the presence of a ...

comprehensive) introduction to the basics of conformal eld theory (CFT) in two dimensions. The aim is to develop just enough CFT from the ground up in order to understand and prove the c theorem, which reveals the deep and subtle connection between entropy, CFT ( xed point in RG) and the direction of RG ow between them.

2023年6月22日 · The crystal field theory (CFT) was proposed by H. Bethe and V. Bleck. This theory explains the bonding, properties, electronic spectra, and magnetism of metal complexes more clearly. The conversion of five degenerate d-orbitals of the metal ion into different sets of orbitals having different energies in the presence of a crystal field of ...

What is the Crystal Field Theory? The valence bond theory could not explain the stability of the coordination compounds. It also failed to throw a light on the differences between strong and weak ligands. Therefore, scientists proposed the crystal field theory.
