Controlled step-by-step dissociation of single iodobenzene molecules has been performed at Cu(1 1 1) step-edges using tunneling electrons from a scanning tunneling microscope (STM) tip at 12 K. We show that the threshold tunneling electron energies to break a single bond inside a polyatomic molecule can be determined by using I-V spectroscopy of single molecules. Electron energies of 1.5 ± 0.1 eV are necessary to break the σC-I bond. This selective bond breaking procedure is possible due to the inherent bond energy differences inside the molecule. It requires electron energies of 3.1 ± 0.1 eV or higher to further disrupt the π ring. © 2003 Elsevier Science B.V. All rights reserved.
