Class Summary 09/17/04

09/17 Total Spin of a System

Hartree-Fock Approaches (Restricted and Unrestricted)

Total Spin of a System

Restricted Hartree-Föck (RHF) Electrons get paired into the same orbital(s), e.g. 4 electrons would go into 2 orbitals

Unrestricted Hartree-Föck (UHF) Electrons do not get paired, e.g. 4 electrons would go into 4 orbitals

Föck Matrix, general form where you have n e^-’s, n/2 orbitals and spin S=0
