    • In the calculations, d denotes the distance between the O atom of the unrelaxed tip (i.e., for Δx = 0) and the plane of the imaged atoms. In the experiment, the tip height was measured with respect to the STM set point; therefore, there is an offset with respect to d. Comparison with theory (10, 28) shows that the minimum of Δf(d) above a carbon ring is usually found at d = 3.9 Å. By measuring the tip height that yielded the minimum of Δf(z) in the experiment and by setting this height to z = 3.9 Å, we determined the offset and adjusted all other tip heights of a measurement series by applying the same offset. Therefore, the experimental z values correspond to the theoretical d values and approximately reflect the atomic tip-sample separation.

    • 60 and HBC could not be stably imaged by AFM on NaCl films with atomic resolution because they were laterally manipulated when using small tip heights. In contrast, DBNP could be imaged on bilayer NaCl on Cu(111) and was investigated on this surface to demonstrate that bond-order discrimination is possible on different substrates.

    • 60, resulting in additional lateral distortions. However, the p and h bonds can be compared with each other because of their similar vdW background.
