Quantum orbital splitting diagram

FIG U RE 5.13 Correlation diagram for electronic states leading to the three lowest asymptotes of K2. States at short intemuclear distances are desciihed hy Hund s case (a) or (h) quantum numbers. As R increases, the components of the short-distance states split into a variety of Hund s case (c) states, especially as the spin-orbit splitting of the 4p state exceeds the magnitude of the interaction potential.

Energy level diagram of the sodium atom. The energy levels are denoted by the values for the principal quantum number , the orbital quantum number/, and the spin quantum number s. Levels with 1 = 0 are not split for / = 1 two separate levels are drawn (s = 1/2) for/> 1 the splitting is too small to be shown in the figure. Wavelengths of a few special transitions are given in nanometers. 

Fig. 2. Correlation diagram of the doublet states between weak (left) and strong (right) spin-orbit coupling. In the strong coupling limit the splitting pattern is determined by the pseudo-./ quantum number...
