Coupling occurs between the resultant spin and orbital momenta of an electron which gives rise to J the total angular momentum quantum number. Multiplicity occurs when several levels are close together and is given by the formula (2S+1). The Russell Saunders term symbol that results from these considerations is given by: (2) (2 S + 1) L

That means we calculate: L total = l 1 + l 2 +. The interaction between L and S is known as LS coupling, Russell–Saunders coupling (named after Henry Norris Russell and Frederick Albert Saunders, who described this in 1925.) or spin-orbit coupling. Atomic states are then well described by term symbols of the form Coupling occurs between the resultant spin and orbital momenta of an electron which gives rise to J the total angular momentum quantum number. Multiplicity occurs when several levels are close together and is given by the formula (2S+1).

The centrality of LS coupling in the analysis and theoretical interpretation of atomic spectra has led to the acceptance of notations and nomenclature well adapted to discussions of particular structures and spectra [ 2 ].
