The dipolar and quadrupolar hyperfine coupling constants, $A$ and $B$, respectively, and the atomic ${g}_{J}$ factor have been measured for the $^{4}S_{\frac{3}{2}}$ ground state of atomic nitrogen 14. An atomic hydrogen maser oscillating at the $\ensuremath{\Delta}{M}_{F}=\ensuremath{-}1$ transition in a magnetic field ranging from 0.008 to 8 G was used as a detector of transitions in both hydrogen and nitrogen. The magnetic field was calibrated by the hydrogen Zeeman transition frequency. Values of the constants were found to be $A=10450929.12(10)$ Hz, $B=1.27(10)$ Hz, and ${g}_{J}=2.002134652(64)$. These results are compared to current theoretical results and other experimental measurements. |
