  text: A direct measurement of the potential energy surface that characterizes individual
    chemical bonds in complex materials has fundamental significance for many disciplines.
    Here, we demonstrate that the energy profile for metallic single-atom contacts
    and single-molecule junctions can be mapped by fitting ambient atomic force microscope
    measurements carried out in the near-equilibrium regime to a physical, but simple,
    functional form. We extract bond energies for junctions formed through metallic
    bonds as well as metal–molecule link bonds from atomic force microscope data and
    find that our results are in excellent quantitative agreement with density functional
    theory based calculations for exemplary junction structures. Furthermore, measurements
    from a large number of junctions can be collapsed to a single, universal force–extension
    curve, thus revealing a surprising degree of similarity in the overall shape of
    the potential surface that governs these chemical bonds. Compared to previous
    studies under ambient conditions where analysis was confined to trends in rupture
    force, our approach significantly expands the quantitative information extracted
    from these measurements, particularly allowing analysis of the trends in bond
    energy directly.
