The methodology presented in this work has been built on the computational results available in the Cartesian Hessian, the concept is parallel to the one presented by Seminario in his FUERZA method. This author demonstrated how to derive the internal force constants for chosen bonds and angles (with sufficient accuracy), by the procedure beyond the normal mode analysis. The goal of this present work is similar, however it is considerably broader, more intricate, and reaching deeply into the nature of the interactions between atoms. The Cartesian Hessian has once again been explored as reliable source of data with facile computational access. By exploring the vector analysis (divergence of force, rather than the ordinary derivatives), the Cartesian Hessian (3n x 3n) is contracted to the Density Functional connectivity matrix (n x n) whose elements not only describe all mutual interactions between atoms nested inside their molecular environment, but also report the electronic energy exclusively.
