“…Numerous measurements of magnetic moments of neutral atoms have been performed using the Rabitechnique [4]: A Stern-Gerlach force acting on an atomic beam in an inhomogeneous magnetic field separates different spin states in space. Transitions between different Zeeman substates are induced in a homogeneous magnetic field region and are monitored by a deflection in a second inhomogeneous B-field.…”

The magnetic moment of the electron, expressed by the g-factor in units of the Bohr magneton, is a key quantity in the theory of quantum electrodynamics (QED). Experiments using single particles confined in Penning traps have provided very precise values of the g-factor for the free electron as well as the electron bound in hydrogen-like ions. In this paper the status of these experiments is reviewed. The results allow testing calculations of higher order Feynman diagrams. Comparison of experimental and theoretical results for free and bound particles show no discrepancy within the limits of error, thus representing to date the most sensitive test of QED. Moreover, the g-factor provides a unique access to fundamental constants, as e.g. the electron mass or the fine structure constant.

“…Stern and Gerlach (Gerlach, 1922) proved that the electron-magnetic moment of an atom in an external magnetic field originates only in certain directions in the experiment in 1922. Uhlenbek and Goudsmit found that the connection between the magnetic moment and spin angular momentum of electron (Uhlenbek, 1925), Rabi and Breit found the transition between the energy levels in oscillating magnetic field (Rabi, 1938). This also proved to be observed in the event of the first magnetic resonance.…”

“…This period is called Rabi period, with ω R being the Rabi frequency, as these equations were derived on the basis of the so-called rotating wave approximation by Rabi (1937) (see also Rabi et al (1938)) in the context of early nuclear magnetic resonance experiments (in beams, with a magnetic dipole transition matrix element V , of course).…”

The basic experimental and theoretical concepts underlying molecular spectroscopy are presented. The equations and relations needed in practical applications of high‐resolution spectroscopy are provided. Group theoretical tools and their use in high‐resolution spectroscopy are introduced and illustrated by simple examples. Time‐dependent processes and quantum dynamics are presented and discussed in relation to spectroscopic observations. Coherent and incoherent radiative excitation and radiationless transitions are treated in relation to applications in molecular spectroscopy.

A New Method of Measuring Nuclear Magnetic Moment

Abstract: To apply these ideas a beam of molecules in a 'Z state (no electronic moment) is spread by an inhomogeneous magnetic field and refocused onto a detector by a subsequent field, somewhat as in the experiment of Kellogg, Rabi and Zacharias. ' As in that experiment the reorienting
