Electronic magnetic dipole orbital angular momentum

Just as orbital angular momentum L gives rise to a magnetic dipole moment pL, spin angular momentum S gives rise to a spin magnetic dipole moment fis. Dirac s relativistic theory of the electron showed that... [Pg.277]

In this Hamiltonian (5) corresponds to the orbital angular momentum interacting with the external magnetic field, (6) represents the diamagnetic (second-order) response of the electrons to the magnetic field, (7) represents the interaction of the nuclear dipole with the electronic orbital motion, (8) is the electronic-nuclear Zeeman correction, the two terms in (9) represent direct nuclear dipole-dipole and electron coupled nuclear spin-spin interactions. The terms in (10) are responsible for spin-orbit and spin-other-orbit interactions and the terms in (11) are spin-orbit Zeeman gauge corrections. Finally, the terms in (12) correspond to Fermi contact and dipole-dipole interactions between the spin magnetic moments of nucleus N and an electron. Since... [Pg.278]

An elementary particle, besides its orbital angular momentum, may also have internal angular momenrnm, or spin cf. p. 29. In Chapter 3, the Dirac theory led to a relation between the spin angular momenmm s of the electron and its dipole magnetic moment Mgpin.el [Eq.(3.63),p. 134] ... [Pg.755]

The gyromagnetic factor is twice as large as that appearing in the relation between the electron orbital angular momentum L and the associated magnetic dipole moment ... [Pg.757]

It is exactly twice as much as we get for the orbital angular momentum and the corresponding orbital magnetic dipole (hence the anomalous magnetic spin moment of the electron), see eq. (12.53). [Pg.122]

The electron Zeeman interaction involves the interaction of the magnetic dipole moment associated with the spin and orbital angular momentum of the unpaired electron with an externally applied magnetic field. The magnitude of this interaction is described by a 3 X 3 g matrix (B.g.S). [Pg.107]
