The most important equation, derived in this work, is the extended Born-Handy formula, valid in the adiabatic limit as well as in the case of break down of the B-0 approximation. Since due to the many-body formulation the extended Born-Handy formula can be expressed in the CPHF compatible form, the extended CPHF equations, describing the non-adiabatic systems, will immediately follow from the presented theory. We shall call them COM CPHF equations. Whereas in the adiabatic limit the extended Bom-Handy formula represents only small corrections to the system total energy, in non-adiabatic systems it plays three important roles (1) removes the electron degeneracies, (2) is responsible for the symmetry breaking, and (3) forms the molecular and crystalline stmcture. [Pg.544]
