WebJan 1, 2010 · For graphite structures under in-plane deformation, the atomistic interaction is mainly governed by the bond stretching and bond angle bending therefore, the dihedral … In molecular physics, the van der Waals force is a distance-dependent interaction between atoms or molecules. Unlike ionic or covalent bonds, these attractions do not result from a chemical electronic bond; they are comparatively weak and therefore more susceptible to disturbance. The van der Waals force quickly vanishes at longer distances between interacting molecules.
