Density-functional thermochemistry. III. The role of exact exchange
Despite the remarkable thermochemical accuracy of Kohn–Sham density‐functional theories with gradient corrections for exchange‐correlation [see, for example, A. D. Becke, J. Chem. Phys. 96, 2155Expand
A New Mixing of Hartree-Fock and Local Density-Functional Theories
Previous attempts to combine Hartree–Fock theory with local density‐functional theory have been unsuccessful in applications to molecular bonding. We derive a new coupling of these two theories thatExpand
A Simple Measure of Electron Localization in Atomic and Molecular-Systems
We introduce in this work a new approach to the identification of localized electronic groups in atomic and molecular systems. Our approach is based on local behavior of the Hartree–FockExpand
A multicenter numerical integration scheme for polyatomic molecules
We propose a simple scheme for decomposition of molecular functions into single‐center components. The problem of three‐dimensional integration in molecular systems thus reduces to a sum ofExpand
Density‐functional thermochemistry. IV. A new dynamical correlation functional and implications for exact‐exchange mixing
A new dynamical correlation functional is constructed subject to a small number of simple, yet key, requirements not all satisfied by existing functionals in the literature. The new functional givesExpand

TLDR
This Perspective outlines the history, basic concepts, and present status of KS-DFT in chemical physics, and offers suggestions for its future development. Expand
Density Functional Calculations of Molecular Bond Energies
The calculation of molecular bond energies is a sensitive test of exchange‐correlation approximations in density functional theory. The well known local density approximation (LDA) gives excellentExpand
Density-functional thermochemistry. I. The effect of the exchange-only gradient correction
Previous work by the author on diatomic molecules and by others on polyatomic systems has revealed that Kohn–Sham density‐functional theory with ‘‘gradient corrected’’ exchange‐correlationExpand
A simple effective potential for exchange.
TLDR
A remarkably simple approximate effective potential is found that closely resembles the Talman-Shadwick potential in atoms and depends only on total densities and requires no two-electron integrals. Expand
