[HTML][HTML] Repulsive tip tilting as the dominant mechanism for hydrogen bond-like features in atomic force microscopy imaging
Experimental atomic force microscopy (AFM) studies have reported distinct features in
regions with little electron density for various organic systems. These unexpected features
have been proposed to be a direct visualization of intermolecular hydrogen bonding. Here,
we apply a computational method using ab initio real-space pseudopotentials along with a
scheme to account for tip tilting to simulate AFM images of the 8-hydroxyquinoline dimer and
related systems to develop an understanding of the imaging mechanism for hydrogen …
