![Quantitative measurements of the C═O***H–C bond: (A) schematic drawing of the hydrogen bonding measurement on trifluorantheno[3.3.3]propellane with a CO-functionalized tip; right shows the AFM image. Scale bar - 300 pm; (B) 2D frequency shift map; (C) calculated force and (D) potentials. Inset shows the same area with a wider contrast. The z origin was set at the position of the hydrogen atom.
