Derive the allowed states of a (3p) 1(4s) configuration in (i) LS coupling and (ii) jj coupling, sketching an energy level diagram in JJ-coupling. As we have seen above, the spin-orbit coupling depends very strongly upon the nuclear charge and for very heavy atom it may outweigh the electrostatic interaction H es . In the perturbation approach, it is then necessary to first consider the influence from H s-o and then, as an additional perturbation, consider H es .

PA322 $\begingroup$ As an aside: it's important to note that, in actual practice, the LS and JJ coupling schemes don't take as inputs the orbital and spin angular momenta of individual electrons: instead, they take in entire subshells. jj coupling hierarchy: the term symbols L and S are no longer good quantum numbers Only j 1, j 2, …, J are good quantum numbers … is the term symbol in jj coupling.

Spin-Orbit coupling is a small perturbation, applies well for 3d elements. (but not for lanthanides, actinides). • Russel-Saunders-Coupling LS-Coupling.

Keep in mind that the use of LS-coupling vs jj-coupling has an empirical basis. It allows to classify the electronic states that appear in actual atomic spectra. energies to term symbols in the LS-, jj- or some intermediate coupling scheme. But if one now wants to compare results of one code – mind the numerical character of the codes – with results of another code and with a measured spectrum, there is the problem of how to compare LS- and jj-coupling levels. It is not possible to pursue the direct In jj-coupling, however, a standard order [cf.
