In the field of quantum chemistry, other semi-empirical methods, such as MNDO (modified neglect of differential overlap), also exist. These are, in their nature, very similar to Hartree–Fock methods, but the computations of the Hamiltonian and overlap matrix elements are based on semi-empirical formulae.

Ab Initio Methods,nciples” and “ab initio” have been widely used recently. The principal idea of these keywords is to regard many-atom systems as many-body systems composed of electrons and nuclei, and to treat everything on the basis of first principles of quantum mechanics, without introducing any empirical paramet

The TB method has the advantage of being quantum mechanical; therefore one has, in addition to its higher accuracy, information about t

For example, in the usual cases of macroscopic systems, the motion of the atoms and molecules can be regarded simply as heat. That is, the average kinetic energy of
