profiles for E int and E vdW are plotted in Fig. for the (COF1) 2 model. In order to include large displacements representative of AB stacking, these scans extend to 20 Å displacements and use a coarse spacing of 1.0 Å to generate contours. Close-up views of the region up to 3 Å displacements, generated using denser mesh, can be found in Figs. and.
