This video is about the introduction and description of LS and JJ coupling. You can't, at least with out calculating actual solutions. 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.

Teach for America. (2013b). Teaching as leadership framework.

An alternative scheme: j-j coupling In the j-j coupling scheme, in contrast to the L-S method, we assume the spin-orbit interaction is much larger than the electronic repulsion. However, the spin-orbit interactions in these two methods are somewhat different. In theL-Scoupling scheme,

Russell-Saunders (or L - S) coupling; and jj coupling. In the Russell Saunders scheme (named after Henry Norris Russell, 1877-1957 a Princeton Astronomer and Frederick Albert Saunders, 1875-1963 a Harvard Physicist and published in Astrophysics Journal, 61, 38, 1925) it is assumed that: spin-spin coupling > orbit-orbit coupling > spin-orbit In jj-coupling, however, a standard order [cf. Section 2.2] is always as-sumed for the coupling sequence of the individual shells.

Then, with the aid of the spectral data of Group 15 elements, it becomes clear that the assumption of the L-S coupling scheme is no longer valid as we go farther and farther down the Periodic Table. In the second part, we A short video on LS and jj coupling. For more videos see the channel https://www.youtube.com/channel/UCjIsl9vgzOW3YAHeek9KUog Thanks for your question.

This kind of coupling is called L-S coupling or Russell-Saunders coupling, and it is found to give good agreement with the observed spectral details for many light atoms. For heavier atoms, another coupling scheme called " j-j coupling " provides better agreement with experiment.

Clarke, E., & Jacyna, L. S. (1987).

loops. In ls coupling, all the nucleons involved in the loops must have the same third spin component. In jj coupling this is no longer true, as there may be statistical links between particles with opposite third components. In general, the contribution from an N-particle exchange loop is given by:

Correspondence between atomic levels in LS and jj couplings H ector O. Di Roccoa and Julio C. Aguiarb a Facultad de Ciencias Exactas, Universidad Nacional del Centro de la Provincia de Buenos j-j Coupling In light atoms, the interactions between the orbital angular momenta of individual electrons is stronger than the spin-orbit coupling between the spin and orbital angular momenta. These cases are described by "L-S coupling". ), and the size of LS coupling term becomes small. For an extensive example on how LS-coupling is practically applied, see the article on term symbols. jj coupling. In heavier atoms the situation is different.
