  Abstract: The line shape of inelastic   transitions seen in inelastic electron tunneling spectroscopy   (IETS) performed on metal−insulator−adsorbate−metal junctions is   well understood. Recently, there have been reports of   quasi-elastic processes leading to strong wide bands in what   heretofore had been called IETS. It is demonstrated that these   quasi-elastic ionizations, known as orbital mediated tunneling   (OMT) bands, are actually differential in nature. However,   because of the steeply rising elastic background in IETS, and   because of the asymmetric shape of these bands, they often give   the appearance of simple peaks. It is experimentally shown that   the position and width of these false peaks can be used to   reasonably estimate the actual maximum in the density of states   associated with the orbital mediated transition.
