TL;DR: By applying controlled current pulses, the upper Pc ligand in TbPc2 is rotated, leading to the disappearance and reappearance of the Kondo resonance, and reversible switching between two stable ligand orientations by applying a current pulse is made possible.
Lateral Hopping of Molecules Induced by Excitation of Internal Vibration Mode
TL;DR: A theoretical model, which is based on the anharmonic coupling between low-frequency modes and the HF mode combined with electron-hole pair excitation, can explain why the hopping of CO is observed on Pd(110) but not on Cu(110).

TL;DR: The electronic transport properties of Ln-Pc molecules as the active layer in top- and bottom-contact thin-film organic field effect transistor devices exhibited ambipolar semiconducting properties with an electron mobility (mu(e) and a mu(H) of approximately 10(-4) cm(2) V(-1) s(-1).

Single-molecule reaction and characterization by vibrational excitation.
TL;DR: In this article, a controlled chemical reaction of single trans-2-butene molecules on the Pd(110) surface was realized by dosing tunneling electrons from the tip of a scanning tunneling microscope at 4.7 K. The reaction product was identified as a 1,3-butadiene molecule by inelastic electron tunneling spectroscopy.

Excitation of Molecular Vibrational Modes with Inelastic Scanning Tunneling Microscopy Processes: Examination through Action Spectra of cis-2-Butene on Pd(110)
TL;DR: The usefulness of the action spectroscopy as a novel single molecule vibrational spectroscopic method is demonstrated and its selection rules in terms of resonance tunneling are discussed.
