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 ...
