Conceptual Density Functional Theory of Chemical Reactivity

Abstract

A rudimentary treatment of density functional theory (DFT) is presented in this article. Various global and local reactivity descriptors are defined within the broad framework of conceptual DFT. A theory of chemical reactivity is developed in terms of these descriptors and the associated electronic structure principles.
