The test of approximate relation between inter-nuclear distances and vibration frequencies in a few-atomic molecule — •Vladimir Damljanovic — Institute of Physics Belgrade, Pregrevica 118, 11080 Belgrade, Serbia

Recently, the author has found a group of coordinate transformations that are symmetries of the electronic effective potential and the potential seen by nuclei in a molecule subjected to no external fields [arXiv:1111.4788v1]. In the lowest order approximation for the electronic effective potential adapted to these symmetries, one obtains the approximate relation between the equilibrium distances among nuclei in the molecule and its vibration frequencies. In this contribution we have tested this approximation for a variety of simple molecules.
