3. Special properties of complexes

3.1 Magnetism

The vast majority of complexes possess interesting magnetic properties. A pronounced paramagnetism is frequently observed. This results from the presence of unpaired electrons in d or f orbitals. The theories explaining the magnetic properties of complexes have been the subject of numerous well-documented works in the scientific literature . However, practical applications are currently few and far between. The most important is nuclear magnetic resonance imaging...
