  text: Understanding how molecular geometry affects the electronic properties of
    single-molecule junctions experimentally has been challenging. Typically, metal–molecule–metal
    junctions are measured using a break-junction method where electrode separation
    is mechanically evolving during measurement. Here, to probe the impact of the
    junction geometry on conductance, we apply a sinusoidal modulation to the molecular
    junction electrode position. Simultaneously, we probe the nonlinearity of the
    current–voltage characteristics of each junction through a modulation in the applied
    bias at a different frequency. In turn, we show that junctions formed with molecules
    that have different molecule–electrode interfaces exhibit statistically distinguishable
    Fourier-transformed conductances. In particular, we find a marked bias dependence
    for the modulation of junctions where transmission is mediated thorough the van
    der Waals (vdW) interaction. We attribute our findings to voltage-modulated vdW
    interactions at the single-molecule level.
