Gyromagnetic ratio

From NMR Wiki

Gyromagnetic Ratio is defined by:

$\gamma = \frac{e}{2m_p}g = g \mu_\mathrm{N}/\hbar,$

where $\displaystyle e$ is the magnitude of electron charge, $\displaystyle m_p$ is the proton mass, $\displaystyle \hbar$ is reduced Planck constant, $\displaystyle \mu_\mathrm{N}$ is the nuclear magneton, and $\displaystyle g$ is the g-factor of the nucleon or nucleus in question.

Approximate values for some common nuclei are given in the Table below.<ref>Template:Cite book</ref>
