dc.description.abstract We perform emperical calculations of the tunneling current through various small organic molecules sandwiched between gold electrodes by using the Wenzel-Kramers-Brillouin (WKB) approximation. The barrierto tunneling is taken to eb the work function of gold and calculated from a first principles electronic structure code. The current-voltage characteristics of these molecules are compared in the context of exisiting first principles and experimental results. In this model the surface dipole moment, induced by the adsorbed molecule can have asignificant effect on the current and hence dipole moments may be an important property for prediction of the conductance chracteristics of a molecule. en_US
