  text: Biased metal–molecule–metal junctions emit light through electroluminescence,
    a phenomenon at the intersection of molecular electronics and nanoplasmonics.
    This can occur when the junction plasmon mode is excited by inelastic electron
    current fluctuations. Here, we simultaneously measure the conductance and electroluminescence
    intensity from single-molecule junctions with time resolution in a solution environment
    at room temperature. We use current versus bias data to determine the molecular
    junction transport parameters and then relate these to the expected current shot
    noise. We find that the electroluminescence signal accurately matches the theoretical
    prediction of shot-noise-driven emission in a large fraction of the molecular
    junctions studied. This introduces a novel experimental method for qualitatively
    estimating finite-frequency shot noise in single-molecule junctions under ambient
    conditions. We further demonstrate that electroluminescence can be used to obtain
    the level alignment of the frontier orbital dominating transport in the molecular
    junction.
