A thertnall)'-activated transitio?t rate TV betxveen two localized electronicstates is gix'en which bridges the adiabatic limmit, where the two states are mixedwell at the activated lattice configuration, and the non-adiabztic linait, where theyare not even there. Frequency dispe:rsion of lattice vibratjons is fully incorporatedw'hich is i?vaportant to assure irreversibiljty of the systena. Basic qu;ttatities arethe interaction. euaergy J betxveen tlv<: two states atad the average atauplitude D andvelocity 77 of thernaal fluctuations of the energy difference betweerm adiabaticpotentials assocjated wjth these slxates. The senaiclassical condition D>>Ico isasstunaed w'ith coai/D. The pre-exponenfial factor of TV is given as a j'unction ofyanJ'/(Ii) which deTeruaaines the adiabatic linait for )>>1 and the noon-adiabaticIiucait for y<<1. Tlae atfettcpt frequer?cy iua W is given by co/2n which is written asan average of variotus ucorncal-mvaode frequenc?es.
