Energy and the magnetic number

The magnetic quantum number does affect the energy level in the presence of an external magnetic field. This is demonstrated by the Zeeman effect where the number of energy levels and the size of the magnetic potential energy increments are determined by the equation

E_mag = m_l( eħ/2m_e)B_ext

Introduction paragraph, Derivation paragraph, and anywhere

Here "m" is taken as "m_l", whereas in the Wikipedia page "Magnetic moment" m is taken as "m_j", with different meanings. Please reach an agreement between the two pages, or use the unambiguous notation m_l, m_j respectively.Grausvictor (talk) 16:37, 24 May 2016 (UTC)

My textbook states that the format is "m_l", though I do not know how to cite a textbook in wikipedia. — Preceding unsigned comment added by 100.36.118.13 (talk) 01:47, 23 November 2016 (UTC)

Magnetic Moment is not the same as Magnetic quantum number. The total magnetic moment "m_j" of the electron is the addition of the spin magnetic moment 'm_s' with the angular magnetic moment m_l. 'Magnetic quantum number' is always m_l. The regular page of Quantum Numbers on Wikipedia explains the material of the quantum numbers a lot better. Bonnom (talk) 13:37, 6 December 2018 (UTC)

the magnetic quantum number is always an integer

i feel like this should be specified in the introductory paragraph, a lot of my classmates didn't get this. 24.132.242.170 (talk) 12:21, 30 October 2016 (UTC)

complete and unique quantum state

The article says: complete and unique quantum state which doesn't seem quite right. Since a linear combination of states is also a solution of the appropriate equation, one can choose a different basis for a just-as-valid quantum state. This is especially important if a different basis is more visual. The p orbitals are commonly described with the x, y, and z basis, not the ones with unique $m_{l}$ values.

I this it is correct to say the state is a "complete and unique". This is just a way of saying that if we fix these quantum numbers then we have a full solution of the Schrödinger equation in a spherical potential. Note that $m_{l}$ is the eigenvalue of $L_{z}$ operator, so this presupposes that we have also fixed the z-coordinate. The degeneracy of the p states, and the related possibility of forming an alternative basis set does not really matter. However, the word "unique" does not really have any information content here, so I will remove it. Jähmefyysikko (talk) 21:36, 24 December 2021 (UTC)
