This section defines the electronic Hamiltonian that is to be used. Within the Born-Oppenheimer approximation the generic form of the electronic Hamiltonian is. H = ∑ i h ( i) + 1 2 ∑ i ≠ j g ( i, j) + V N N; V N N = 1 2 ∑ A ≠ B Z A Z B R A B. where V N N is the operator of the repulsion of classical nuclei.
