Crystal field theory was proposed by H.beths (1929) and Van Vleck (1932) and as originally applied to ionic crystals to explain their optical properties and is, therefore, called crystal field theory, however, this theory was applied to the study of coordination compounds in 1950 and this theory accounts for more satisfactory expalnation for the properties of complexes especially colour and magnetism.
