A hydrogen bond forms between a propellane (lower molecule) and the carbon monoxide functionalized tip of an atomic force microscope. The measured forces and the distance between the oxygen atom at the AFM tip and the propellane’s hydrogen atoms correspond precisely to the calculations.

Scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope, AFM. Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. H-bonds are responsible for specific properties of proteins or nucleic acids and, for example, also ensure that water has a high boiling temperature...
