In the LS-coupling scheme, we analyse multielectron atoms by first applying the central-field approximation, and thereafter treating the multitude of angular momentum interactions as perturbations, in decreasing order of magnitude.LS-coupling is the specific limiting case of this one where we assume that we can first apply solely the angular contribution of the electrostatic LS Coupling jj Coupling 9.

Sanchez Functional Hybrid Materials Related Titles from WILEY-VCH Ajayan, P., Schadler, L. S., Br 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, Next, we use two worked examples to demonstrate the derivation of electronic states with the j-j coupling scheme. Finally, the correlation between the states derived by L-S and j-j schemes is In this case, the individual coupling between the electrons, via the spin-orbit interaction, is stronger than the electrostatic interaction between them. example with a 2-electron atom: Then, j 1 and j 2 couple to a total J. This situation is called “jj-coupling”. The procedure to find the levels resulting from LS and jj couplings for non-equivalen t electrons has been published many times (see [4]).
