Identification of molecular-adsorption geometries and intermolecular hydrogen-bonding configurations by in situ STM manipulation

Abstract

Don't be dim! By combining the technique with DFT calculations, STM manipulation was extended to the probing of intermolecular hydrogen-bonding configurations in self-assembled nanostructures. It was also possible to convert one configuration into another in a controlled fashion through the careful manipulation of a particular structural unit (see picture).
