Abstract: An inflection point is entered in the description of the potential curve (PC). Taking into account the emerging possibilities, the potentials of Mi (n – 6) reduced by the properties of nine substances from globular molecules were analyzed. The observed inconsistencies in the shape of the WF₆ potential was the starting point of the analysis that led to the new notion of companion PCs. It was found that the restored PC with low error is predicted to be critical temperature, and the PC companion is predicted to be critical volume.

Keywords: intermolecular interaction, model potential, potential curve, form factors, inflection point, Mi’s (n – m) potential, critical parameters, globula.
