Quantum-mechanical treatment:
•The dipole moment m of the nucleus is described in quantum-mechanical terms as
•                                      m = g J
•Therein, J is the spin angular momentum and g the magnetogyric ratio of the spin. When looking at single spins we have to use a quantum-mechanical treatment. •Therein, the z-component of the angular momentum J is quantitized and can only take discrete values
•
•
•J is related to spin quantum number of the nuclei I
•         -I,…,o,…,+I
