The vibronic interactions have multiple impacts in various chemical and physical phenomena [1,2]. Especially, the vibronic paradigm is a natural key for the stereochemical problems, to which offers a general methodology and a set of meaningful parameters. 

If we try to fit the factors of the stereochemical distortions in the four types of Aristotle s causes, one may assimilate causa materialis to the particular molecule that offers the problem, then consider causa finalis as tendency of finding the minimum energy, and keeping causa formalis for the symmetry reasons of the problem, one arrives to the vibronic interaction as causa efficiens, i.e., as a driving force of the stereochemistry.
