“…[1][2][3][4] In 1998 Stipe et al demonstrated that rotation of a single isolated acetylene molecule on Cu͑100͒ is induced by vibrational energy transfer from the C-H stretch mode excited by tunneling electrons to the frustrated rotational mode of the molecule. 5 The rotation rate R͑V͒ exhibits a threshold at the bias voltage corresponding to the excitation of the C-H stretch mode.…”

We propose an action spectroscopy for single-molecule motion induced by vibrational excitation with a scanning tunneling microscope ͑STM͒. Calculations of the inelastic tunneling current for excitation of the C-O stretch mode of the CO molecule on metal surfaces are combined with a theory which describes how the energy in the vibrational mode is transferred to a reaction coordinate mode to overcome the activation barrier. The calculated rate for CO hopping on Pd ͑110͒ as a function of the bias voltage agrees with the experimental result. It is proposed that the second derivative of the reaction rate with respect to the bias voltage is related to the vibrational density of states, which usually cannot be directly observed in STM inelastic electron tunneling spectroscopy when a molecule motion is induced by vibrational excitation.

“…However, the reactions can be also induced by electronic excitation or electron (hole) attachment with STM, which takes place at the bias voltage higher than *1 eV [71][72][73][74]. The electronic excitation occurs when tunneling electrons couple with electronic states of the atoms or molecule.…”

I describe a brief summary of quantum mechanics and principles of scanning tunneling microscopy (STM) in this chapter. Quantum tunneling is an important concept to describe the transportation of small particles, like electron and hydrogen. In Sect. 2.1 I focus on H-atom tunneling in a double minimum potential that is the simplest but a ubiquitous system in physics and chemistry. Quantum tunneling of electron directly relates to the principle of the STM. In Sect. 2.2 the principles and applications of STM are described. I focus on the inelastic electron tunneling process in an STM junction, which can be applied to the vibration spectroscopy and reaction control of single molecules.

Umwandlung der absoluten Konfiguration einzelner Adsorbatkomplexe

Chiralitätsumkehr durch Elektronen: Propenmoleküle bilden chirale Komplexe bei Adsorption auf einer Kupferoberfläche. Inelastisch gestreute Tunnelelektronen aus der Spitze eines Rastertunnelmikroskops regen molekulare Schwingungen an, die zur Rotation oder Diffusion des Adsorbats auf der Oberfläche führen. Bei höheren Tunnelströmen wird auch die Umwandlung in die entgegengesetzte Konfiguration beobachtet.
