The Royal Society of Chemistry reports that the imaging technique involved oscillating a probe over the molecules at the resonant frequency of the surface beneath them. By measuring the difference in frequencies between the surface alone and the one with the molecule, the researchers were able to create a highly precise image of the bond.
