Abstract
Properties of molecular electron density functionals are studied. The Kohn potential can be considered as the potential density of the system′s particles whose integration gives the energy of the molecule′s quantum state. Unambiguous expressions for molecular electron energies are obtained in the form of the Kohn potential integrals using a simplified wave density model based on the nuclear wave density isolation. A one-electron Schrödinger equation with an effective potential for calculating molecular orbitals is presented. The equation can be used to calculate 3D electron density of molecules in ground and excited states.
期刊介绍：
Journal is an interdisciplinary publication covering all aspects of structural chemistry, including the theory of molecular structure and chemical bond; the use of physical methods to study the electronic and spatial structure of chemical species; structural features of liquids, solutions, surfaces, supramolecular systems, nano- and solid materials; and the crystal structure of solids.
