2. Scientific and technological aspects
The physical properties of the sodium nucleus ( 23 Na) allow it to be detected by NMR and, consequently, salt (NaCl) to be analyzed by NMR spectroscopy and imaging. When a salty sample is placed in an intense, static magnetic field, a macroscopic magnetization appears in the sample parallel to the field. This results from the distribution of all sodium nuclei between different energy levels at thermodynamic equilibrium.
by "set" we mean a very large number. For example, 1 liter of water at a concentration of 1 M NaCl contains ~ 6 · 10 23 sodium nuclei.
