* >> R is the Rydberg correction << should be a misprint of  >> R is the Rydberg constant <<, 
* in the article there is a certain confusion between excitation energy [these should be the energy levels for Rb] and term energy R/n*^2 that is the ionization energy of the level; this makes unsure my next comment
* by the Hund rule, a less-than-half-filled level should have the lowest j as lowest level. For Rb the data are in the opposite order
* for Rb, 4d-5f is the same of 4d-6f; I feel that 4d-6f should be removed and 4d-7f should be renamed 4d-6f
* in all these articles AND AT LEAST FOR THE ALKALI, there is a confusion between "nd" that represent the level in which the valence electron is promoted and "1D, 2D ..." that represent the first, second ... level with L=l=2,

i.e. 1D=3d 2D=4d ... for Li, Na and K --- 1D=4d 2D=5d ... for Rb --- 1D=5d 2D=6d ... for Cs

I have corrected the "Rydberg correction", and also 4d-6f entry for rubidium, not that values should be moved up, but entries were wrong.

For Rb lowest level is 3/2 and there is also 5/2; the figures in the table match the reference. The absolute values are energy level , not ionisation energy. so 5s is 0.0 Å; 4d 3/2 is 19,355.623 Å

last point is "yes" it is confusing. Graeme Bartlett (talk) 11:50, 13 January 2024 (UTC)[reply]
