The hyperfine coupling
Did you know?
The theory of hyperfine structure comes directly from electromagnetism, consisting of the interaction of the nuclear multipole moments (excluding the electric monopole) with internally generated fields. The theory is derived first for the atomic case, but can be applied to each nucleus in a molecule. Following this there is a discussion of the additional effects unique to the molecular case. WebMar 5, 2024 · It should be noted that different isotopes of a given element in general have different nuclear spins and consequently different hyperfine structure. Whether the electrons in an atom are coupled by L S or j j or intermediate coupling, the coupling between the electrons is much stronger than the weak coupling between electrons and nucleus.

In quantum physics, the spin–orbit interaction (also called spin–orbit effect or spin–orbit coupling) is a relativistic interaction of a particle's spin with its motion inside a potential. A key example of this phenomenon is the spin–orbit interaction leading to shifts in an electron 's atomic energy levels, due to ...
