Abstract: We present a new theoretical approach to determine the interaction energy due to the coupling of adsorbed molecules to their environment in scanning tunneling microscopy. In fact, the above coupling energy is estimated by assuming the involved adsorbed molecules as Morse oscillators and their environment (electrodes, leads) as external reservoir.
