AbstractWe report theoretical investigations of dynamic conductance of molecular systems in the metal-molecule-metal device configuration. The quantum coherent ac transport may be mediated by resonant states extending the entire molecule, or mediated by localized states within the molecule itself. The latter is characterized by tiny features in the dc conductance, but the dissipative part of dynamic conductance can be enhanced by several orders of magnitude as the ac frequency is increased. This phenomenon can be understood from an analytical model.
