https://doi.org/10.1007/b102617hn–Sham equations can be derived, analogously to the Hartree–Fock equations. Finding good functionals is the main problem in DFT. Various levels of DFT and new functionals are discussed. The mutually related concepts of electronic chemical potential, electronegativity, hardness, softness, and the Fukui function are exemplified.

The Concept of the Potential Energy Surface,to focus on the electronic energy and add in the nuclear repulsion energy later; this third point, very important in practical molecular computations, is elaborated on in Chapter 5. Geometry optimization and transition state optimization are explained.

Basic Problems Besetting Clinical Research beyond those of main-group heavy atoms: not only can relativistic effects be significant, but electron d- or f-levels, variably perturbed by ligands, make possible several electronic states. DFT calculations, with pseudopotentials, are the standard approach for computations on such compounds.
