“…Although DFM's "sibling" technique, scanning tunnelling microscopy (STM), has long been capable of submolecular resolution imaging, in the sense that molecular orbital density can be probed (see an earlier volume of this Springer series on Atom and Single Molecule Machines [52]), only DFM is capable of resolving the chemical framework or atomic structure of a molecule. This is because STM probes orbital density only within a specific energy window (set by the potential difference between the tip and sample) and in conventional tunnelling microscopy therefore only the frontier molecular orbitals are accessible 15 .…”

It appears to be one of the few places in physics where there is a rule which can be stated very simply, but for which no one has found a simple and easy explanation. The explanation is deep down in relativistic quantum mechanics. This probably means that we do not have a complete understanding of the fundamental principle involved.RP Feynman, The Feynman Lectures on Physics, Vol III, Chapter 4 (1964) AbstractExceptionally clear images of intramolecular structure can be attained in dynamic force microscopy through the combination of a passivated tip apex and operation in what has become known as the "Pauli exclusion regime" of the tip-sample interaction. We discuss, from an experimentalist's perspective, a number of aspects of the exclusion principle which underpin this ability to achieve submolecular resolution. Our particular focus is on the origins, history, and interpretation of Pauli's principle in the context of interatomic and intermolecular interactions.
