Talk:Zeeman effect
From Wikipedia, the free encyclopedia
Why do levels d,e,f in the first diagram become d,f,g in the second diagram? Is this what the writer intended, or just a typo? -- Heron

Is there a mathematical discription of the Zeeman effect on Wikipedia yet? Something along the lines of: a hydrogen atom in the presense of a 1 1 T magnetic field will have its various energy states shifted by x amount for quantum numbers of n=_, l=_, m=_, etc. -A. O.
It might be worth mentioning that the split Zeeman lines are also polarised - the pi bands are polarised parallel to the magnetic field direction, and the sigma bands are at right angles to the field. Steve Morton.
[edit] Not a Paschen-Back there
What is described in the strong case should be named "normal Zeeman", not Paschen Back. This one should include the spin orbit as a pertubation. Let me know if I'm wrong.
- The strong-field Zeeman effect is also known as the Paschen-Back effect, according to Griffiths, "Introduction to Quantum Mechanics", footnote on p.279 of the 2nd edition. Indeed the spin-orbit correction is still there as a perturbation. HEL 21:13, 29 November 2006 (UTC)
Agreed! In short:
- Paschen-Back: medium B-field, spin-orbit coupling still appreciable. Perturbation next to B-field interactions.
- Normal Zeeman: strong B-field, spin-orbit coupling broken. m_j and m_s decoupled quantum numbers.

Disagreed! Or rather, Schiff writes "The Zeeman effect usually refers to the weak-field case, and the Paschen-Back effect to the strong-field case, although the term Zeeman effect is sometimes used to include all magnetic effects".
