In this video we have explained Crystal Field theory (CFT) which is an important portion in chapter coordination compounds of class 12. 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). ... CFT was developed by physicists Hans Bethe and John Hasbrouck van Vleck in the 1930s. contact us: 8281508957 8921040214
