Our findings provide a way to gain additional information regarding the molecule–electrode interaction, in particular, the interesting interplay between molecular conformation, vibrations and charge transport.

Molecule 3, on the other hand, has a flatter profile for the energy, suggesting that the molecule–electrode interaction is less dependent on the position. The binding energy of junctions with 1

• the molecule–electrode interaction, presumably caused by a change in molecular conformation. A similar change in molecular conformation was also observed in the room temperature I(V)s as demonstrated by the red and black curves in Figure 2; the onset for the current increase shifted by −100 mV and the

• the molecule–electrode chemical bond nor the electrode configuration itself can be held responsible. More likely, varying the electrode distance changes the molecular conformation, which in turn leads to abrupt changes in the molecule–electrode interaction. Our findings also show that I(V
