Magnetic dipole moment of the deuteron — the nucleus of deuterium (heavy hydrogen), one proton bound to one neutron.

Sets how strongly the particle lines up in a magnetic field — the quantity behind NMR, MRI and precision spectroscopy. A negative sign means the moment points opposite to the spin. Its ratios to the Bohr and nuclear magnetons and to other particles' moments are listed beneath.

Also listed by NIST as: Deuteron g factor — the same value and unit.
