Abstract

The anharmonic chemical field potential, V (Ø,χ ,η ), is expressed in terms of the electrostatic potential, ø , the electronegativity, χ, and the chemical hardness, η, density functionals, as they relate the electron density functional, ρ, and chemical bond formation by quantum field/operators [observable/measurable quantities (physical observables)].

Keywords: Anharmonic potential, chemical field, chemical hardness, electron density, electronegativity, electronic potential, Feynman-Kleinert path integral, symmetry breaking.
