• intermolecular interactions between adjacent molecules due to hydrogen bonding [1][2][3][4], covalent bonding [5][6], or, in the case of metal organic networks, by metal–ligand interactions [1][7][8][9]. In these cases, the interactions between the adlayer and the substrate, or more specifically, the local

• charges and of permanent or induced dipoles. The third category covers bonding forces, which have a quantum mechanical nature. These forces lead to charge transfer processes as involved in covalent bonding. Furthermore, this category includes the repulsive exchange forces, which are caused by the Pauli
