Bf In the optical frequency regime, magnetic dipole tran-sitions are orders of magnitude weaker than their electric dipole counterparts 1–3. ) The hyperfine structure of the hydrogen spectrum is explained by the interaction between the magnetic moment of the proton and the magnetic moment of the electron, an interaction known as spin-spin coupling.
The measured magnetic moment of low-spin d 6 Fe(CN) 6 4− confirms that iron is diamagnetic, whereas high-spin d 6 Fe(H 2 O) 6 2+ has four unpaired electrons with a magnetic moment that confirms this arrangement. It requires the transition magnetic moment µB(3/2)→B(1/2). Magnetic dipole transitions describe the dominant effect of the coupling to the magnetic part of the electromagnetic wave.
