Abstract
The adiabatic potential of an arbitrary polycentre system with multimo de vibronic interaction at each centre is investigated. It is shown th at in the case when the extrema of this adiabatic potential are consid ered, an effective Hamiltonian for the static Jahn-Teller effect depen ding only on active one-centre nuclear displacements can be proposed. The expressions for the parameters of this Hamiltonian are obtained an d its symmetry properties are elucidated.
