The single Slater determinant wavefunction (properly spin and symmetry adapted) is the
starting point of the most common mean field potential. It is also the origin of the molecular

common:
1. A minimal basis in which the number of STO or CGTO orbitals is equal to the number
of core and vale

Thus, the product of two GTOs on different centers is equal to a single other GTO at a

III. The Unrestricted Hartree-Fock Spin Impurity Problem
As formulated above in terms of spin-orbitals, the Hartree-Fock (HF) equations
yield orbitals that do not guarantee that possesses proper spin
where the so-called Fock operator F is given by
F i = h i + j(occupied) [Jj - Kj] i .
The coulomb (Jj) and exchange (Kj) operators are defined by the relations:
Jj i = *j(r') j(r')1/|r-r'| d' i(r) , a
(it can be shown, in general that i,j,k,l is odd under exchange of i and j, odd under
exchange of k and l and even under (i,j)<=>(k,l) exchange; this implies that i,j,k,l
vanishes if i = j or k = l.)
where h is the one-electron component of the Hamiltonian (i.e., the kinetic energy operator
and the sum of coulombic attractions to the nuclei). The operator Jj,l is defined by:
