Kucherenko М.G., Chmereva T.M. , Kislov D.А. INCREASE OF RADIATIONLESS ELECTRONIC EXCITATION ENERGY TRANSFER RATE BETWEEN MOLECULES PLACED NEAR A SOLID FLATE SURFACEA radiationless electronic excitation energy transfer between molecules placed near a conductor flat surface is investigated. A mathematical model is proposed where the condensed phase boundary taken into account by introduce of an effective dipole-imagine and the medium dielectric permeability on the electronic transfer frequency in the donor molecule. A distance dependence and anisotropy characteristics of the energy transfer rate are determined in the donor-acceptor pare of adsorbates. In a purely quantum model based on the secondary quantization formalism it is showed that a mechanism of surface plasmons can be effective for the energy transfer in such systems. Comparative estimates of direct and plasmonic energy transfer channels efficiencies are made. The dominant contribution of the plasmonic mechanism to total energy transfer rate (over 1-2 power) is predicted by placed molecules near the metal surface and a weak plasmon decay. Key words: radiationless energy transfer, surface plasmon, dipole-dipole interaction, donor, acceptor.
