Abstract

The Born-Oppenheimer approximation gives the possibility of understanding the essence of chemical transformations and other rate processes, including those occuring in condensed media. According to this approximation, the motion of nuclei, atoms and molecules may be described by the effective potential energy. This potential energy coincides with the electronic energy Uα averaged over the electronic eigenstate a (see (1.91)). For given electronic state α we may describe the motion of nuclei by the Hamiltonian which depends only on nuclear coordinates q
$$H = T + {U_{2}}\left( q \right)$$
