WebAb initio DFT is a new method for obtaining approximate solutions to Eq. 1-3. Its formalism is based on two fundamental electronic structure approaches : ab initio wavefunction methods and Density Functional Theory. 3 1.1 Ab-Initio Wavefunction-Based Methods Hartree-Fock Method. WebDFT, ab initio and semi-imperical such as AM1 and PM3 are quantum mechanics (QM) methods. QM is the correct mathematical description of the behavior of electrons and thus of chemistry.
