He did some work in atomic physics, particularly on the laser and measuring the gyromagnetic ratio of the electron.

The gyromagnetic ratio for a free electron has been experimentally determined as .

The symbol Γ' is used for the measured gyromagnetic ratio using conventional electrical units.

The term "gyromagnetic ratio" is sometimes used as a synonym for a different but closely related quantity, the g-factor.

The g-factor, unlike the gyromagnetic ratio, is dimensionless.

Protons, neutrons, and many nuclei carry nuclear spin, which gives rise to a gyromagnetic ratio as above.

This procedure gives observables in very close agreement with experiment as seen e.g. for electron gyromagnetic ratio.

One of these frequencies is the anomaly frequency, which has played an important role in the measurement of the gyromagnetic ratio of the electron.

But Tyndall invited Chattock back after the war in 1919 where he carried out definitive experiments on the gyromagnetic ratio of iron.

Hans Dehmelt et al. tested the anomaly frequency, which plays a fundamental role in the measurement of the electron's gyromagnetic ratio.

The value of g is exactly equal to one, by a quantum-mechanical argument analogous to the derivation of the classical gyromagnetic ratio.

What is more, the value of the gyromagnetic ratio of the electron, standing in front of Pauli's new term, is explained from first principles.

It arises naturally in a number of physical problems, including in the second- and third-order terms of the electron's gyromagnetic ratio using quantum electrodynamics.

The constant is the Gilbert phenomenological damping parameter and depends on the solid, and is the electron gyromagnetic ratio.

The most precise values of the fine structure constant come from comparisons of the measured and calculated value of the gyromagnetic ratio of the electron.

The sensitivity of NMR signal detection depends on the gyromagnetic ratio (γ) of the nucleus.

He also researched the photoelectric effect, the Gyromagnetic ratio, the emission of electrons by chemical reactions, soft X-rays, and the spectrum of hydrogen.

The resonant frequency of each isotope is directly proportional to the strength of the applied magnetic field, and the magnetogyric or gyromagnetic ratio of that isotope.

The relaxation time, T (the average lifetime of nuclei in the higher energy state) is dependent on the gyromagnetic ratio of the nucleus and the mobility of the lattice.

A g-factor (also called g value or dimensionless magnetic moment) is a dimensionless quantity which characterizes the magnetic moment and gyromagnetic ratio of a particle or nucleus.

The relationship between the frequency of the induced current and the strength of the magnetic field is called the proton gyromagnetic ratio, and is equal to 0.042576 Hz nT.

The gyromagnetic ratio of a nucleus is particularly important because of the role it plays in nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI).

For example, the gyromagnetic ratio of C is 4 times lower than the proton, so the signal intensity it produced will be 64 times lower than that of a proton.

Alternative methods are therefore necessary for nuclei with a negative gyromagnetic ratio, and one such method using the INEPT pulse sequence was proposed by Ray Freeman in 1979.

Hydrogen is the most frequently imaged nucleus in MRI because it is present in biological tissues in great abundance, and because its high gyromagnetic ratio gives a strong signal.
