Intrinsic angular momentum of a nucleus (or other sub-atomic particle).
Notes:
- The magnitude of nuclear spin is \((h/2\pi)\sqrt{I(I + 1)}\) where \(I\) is the spin quantum number and \(h\) is the Planck constant.
- In nuclear magnetic resonance spectroscopy, only nuclei with spin \(I \gt 0\) are observable.
- The spin of a nucleus is dependent on the numbers and alignments of the spins of its individual protons and neutrons.
- Nuclei with a spin of \(½\) generate the simplest nuclear magnetic resonance spectra and are thus the most commonly studied.
