Molecular interactions from the density functional theory for chemical reactivity: Interaction chemical potential, hardness, and reactivity principles

open access: yesFrontiers in Chemistry, 2022
In the first paper of this series, the authors derived an expression for the interaction energy between two reagents in terms of the chemical reactivity indicators that can be derived from density functional perturbation theory.

Molecular Electron Density Theory: A Modern View of Reactivity in Organic Chemistry

open access: yesMolecules, 2016
A new theory for the study of the reactivity in Organic Chemistry, named Molecular Electron Density Theory (MEDT), is proposed herein. MEDT is based on the idea that while the electron density distribution at the ground state is responsible for physical ...

Comparative Study of Planar Octahedron Molecular Structure via Eccentric Invariants

open access: yesMolecules, 2023
A branch of graph theory that makes use of a molecular graph is called chemical graph theory. Chemical graph theory is used to depict a chemical molecule. A graph is connected if there is an edge between every pair of vertices.
