Two-site single electron system interacting with many vibrating ions of a lattice via a long-range
(Frohlich) electron-phonon interaction is studied in the adiabatic regime. The renormalised hopping
integral of small adiabatic Frohlich polarons is calculated and compared with the hopping integral
of small adiabatic Holstein polarons.
