# Because of this coupling, the one electron wavefunctions . lm sm l s which are the eigenfunctions of H 0 are no more the eigenfunctions of the total Hamiltonian . H The eigenfunctions of the Hwill be . Jm. J. which are the coupled wavefunctions and can be derived from the uncoupled wavefunctions . lm sm. l s, as described in previous lectures.

The energy levels which are characterised by certain values of L and S are called terms and the coupling of angular momenta of individual electrons to a resulting orbital angular momentum and spin is referred to as LS-coupling or Russell-Saunders coupling.

Its form in terms of standard unit operators acting within a space of one shell is obtained. The interaction between the quantum numbers L and S is called Russell–Saunders coupling (after Henry Norris Russell and Frederick Saunders) or LS coupling. Then S and L couple together and form a total angular momentum J: = +, where L and S are the totals: In general, J = L + S. For small atoms, LS coupling dominates the angular momentum related component of the Hamiltonian. That means we calculate: L total = l 1 + l 2 + . S total = s 1 + s 2 + . and then, J total = L total + S total. For larger atoms we calculate j = l + s for each electron before summing: J total = j 1 + j 2 + .

## For small atoms, LS coupling dominates the angular momentum related component of the Hamiltonian. That means we calculate: L total = l 1 + l 2 +. S total = s 1 + s 2 +.

there that the ZORA Hamiltonian is bounded from below for. Coulombic potentials.

We therefore can form the following terms: low-energy solutions of the exact electronic Hamiltonian [i.e., energies and wavefunctions in Eq. (1)] as precisely as possi-ble.[45] These N selected or targeted lowest solutions of the exact electronic Hamiltonian form a subspace (of the total space H) called target space T spanned by the solutions which are defined as Hj^ W ii5E jW i (1) LS coupling is one of the approximation schemes that works for light atoms.

In the following This kind of coupling is called L-S coupling or Russell-Saunders coupling. 2.
