Apart from being an experimental observable and a basic input to DFAs, ρ(r) serves as a descriptor for various chemical analyses, including molecular electrostatic potential maps , electron localization functions , and the Quantum Theory of Atoms in Molecules (QTAIM) . The QTAIM formalism provides an inspiration for the widely used visualization of noncovalent interactions (NCI) based on the gradient and Hessian of ρ(r). The NCI analysis enables visualization of a broad variety of noncovalent interactions, such as hydrogen bonds and vdW dispersion. Typically, the NCI analysis relies on self-consistent DFA densities or even additive atomic densities , neglecting vdW-induced polarization. Although regions contributing to dispersion interactions can be glanced from semilocal densities, the reliance on "vdW-lacking" densities has been recognized by the community as one of the key shortcomings .
