Abstract The theoretical expressions for the magnetic susceptibility and g ‐values of trigonally distorted octahedral V 3+ ion have been developed on the basis of molecular orbital method of Stevens [19] and Bose et al. [20]. Results are discussed considering the less strong vibronic coupling (dynamic Jahn‐Teller effect) in which an orbital triplet interacts with the vibrational E‐modes of the ligands. Comparison is made with experimental results on magnetic susceptibility, g ‐values, and optical absorption with a unique set of values of parameters in the theoretical expressions at all temperatures. The Jahn‐Teller coupling parameter appears to be appreciable in some of the complexes.
