It is shown that the Jahn‐Teller equivalent configurations of a threefold degenerate electronic T‐term do not seem to correspond to pure tetragonal or pure trigonal distortions as expected from the work of Opik and Pryce [10]. The conclusions of the latter work appear to be valid only to first approximation. The distortions of tetragonal minima under trigonal displacements are obtained. This shows that inversion splitting does occur as predicted earlier [1], in contrary to the statements of Ham [9]. The results of the theory are in agreement with the last experiments by Sturge [8].
