Dispersion interactions might initially appear unimportant in chemistry due to their relatively weak nature. Although these interactions are indeed approximately 100 times weaker than covalent bonds, their additive character, long-range effect, and the fact that they are always attractive in character make them significant even in medium-sized systems. Thus, a profound impact of dispersion interactions can be observed not only in weakly interacting noble gas aggregates and condensed phases such as liquids and molecular crystals but also in chemical bond formation and thermochemistry, as it can influence the outcomes of common chemical reactions significantly. At a macroscopic level, dispersion interactions are responsible for phenomena as diverse as coagulation in colloids, and why a gecko can walk up a wall. Density Functional Theory (DFT) is one of the most important methods in computational chemistry today due to its relative computational efficiency and the accuracy of its results. DFT includes local dynamic correlation effects rather well. While some functionals are effectively dispersion-free (e.g. B3LYP describe our search for other instances of the same phenomenon. Turning to analysis, we will then discuss the underlying reasons for this behavior and propose our solution, realized in a slight modification of the original D3 method to yield what we call the D3-Smooth (D3S) scheme. The D3S approach is designed to be smoother than D3 with respect to change as a function of nuclear displacements, while disturbing the final D3 dispersion interactions as little as possible.
