1 INTRODUCTION: Usually we understand from the word coupling is the act of combining two things, here we are going to discuss the coupling in quantum physics. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. 1997-02-07 · ELSEVIER 7 February 1997 Chemical Physics Letters 265 (1997) 490-496 CHEMICAL PHYSICS LETTERS (LS) versus (jj) coupling in P 2p inner-shell excited states of PF3 N. Kosugi a, R.G. Cavell b, A.P. Hitchcock c a lnstituteJbr Molecular Science, Okazaki 444, Japan b Chemistry, University of'Alberta, Edmonton, Alb.. The usual atomic term symbols assume LS coupling (also known as Russell–Saunders coupling or spin-orbit coupling).

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. In the first part of this paper, we review the assumption of the L-S coupling scheme, with which we derive the electronic states arising from a given atomic configuration. 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the aid of the spectral data of Group 15 elements, it becomes clear that the assumption of the L-S coupling scheme is no longer valid as we go farther and farther down the Periodic Table.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 reports both LS-coupling and intermediate-couplingR-matrix calculations, the latter in the BP approximation.

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. Section 2.2] is always as-sumed for the coupling sequence of the individual shells. Several simplifications are used on the basis of this standard order.

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 .
