Quantum chemistry computer programs are used in computational chemistry to implement the methods of quantum chemistry. Most include the Hartree–Fock (HF) and some post-Hartree–Fock methods. They may also include density functional theory (DFT), molecular mechanics or semi-empirical quantum chemistry methods.

Although there is a loose ordering of density functionals from less sophisticated to more sophisticated (e. LDA to GGA to hybrid, etc. ), in practice there is no reliable way to improve your computation by going to the next better functional.

By contrast, this is possible with wavefunction. Abstract. Density functional theory is based on the two Hohenberg-Kohn theorems, which state that the ground-state properties of an atom or molecule are determined by its electron density function, and that a trial electron density must give an energy greater than or equal to the true energy (the latter theorem is true only if the exact functional could be used).
