Hydrogen Fine Structure (400 words) |
 | The small splitting of the spectral line is attributed to an interaction between the electron spin S and the orbital angular momentum L. It is called the spin-orbit interaction. |
| The energy levels of atomic electrons are affected by the interaction between the electron spin magnetic moment and the orbital angular momentum of the electron. |
| Assuming a circular orbit, the angular momentum is mrv, so this field can be expressed in terms of the orbital angular momentum L: For a hydrogen electron in a 2p state at a radius of 4x the Bohr radius, this translates to a magnetic field of about 0.3 Tesla. |

Angular momentum coupling - Wikipedia, the free encyclopedia (1314 words) |
| In atomic physics, spin-orbit coupling describes a weak magnetic interaction, or coupling, of the particle spin and the orbital motion of this particle, e.g. |
| In Nuclear Magnetic Resonance spin-spin coupling is a kind of weak interaction between the spin of a nucleus and the spins of nearby nuclei. |
| Spin-spin coupling or spin-spin splitting is the coupling of the spin angular momentum states of different particles. |
