The book presents the basic theory of the unpaired electron-nucleus coupling and the consequences on nuclear chemical shift and relaxation. The types of information obtained from the various metal ions containing molecules are discussed. One and two dimension NMR experiments for paramagnetic molecules and biomolecules are analysed. Perspectives on the exploitation of partial alignment and cross correlation effects are provided.

From the Preface:
"Applications of NMR to paramagnetic molecules and biomolecules in solution have grown in both number and sophistication as the technology of the instruments has improved. They now represent a respectable share of all NMR activity. For these NMR experiments, the general theory of NMR must be understood and, on top of this, the theory of the electron-nucleus interaction and its consequences for the NMR parameters. Therefore, the field of NMR of paramagnetic molecules has its own niche in the entire scientific panorama. The authors aim to privide an up-to-date report on the state of the field."
The scope is that of presenting a complete description, which is both rigorous and pictorial, of theory and experiments of NMR of paramagnetic molecules in solution. Pertinent examples are described. From the time dependent behaviour of electrons in the various metal ions including polimetallic systems to the hyperfine-based information, and from NMR experiments to constraints for solution structure determination.
Emphasis is given to homocorrelated 1H-1H spectroscopies because the adverse effects of paramagnetism are maximal for protons, due to their largest magnetogyric ratio.
