NMR is a growing technique which represents a generalized, spread, common tool for spectroscopy and for structural and dynamic investigation. Part of the field of competence of NMR is represented by molecules with unpaired electrons, which are called paramagnetic. The presence of unpaired electrons is at the same time a drawback (negative effect) and a precious source of information about structure and dynamics. New phenomena and effects are described which are due to the high magnetic fields and advances in the methodology. Solution NMR of Paramagnetic Molecules is unique in dealing with these matters. 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. The book's major theme is how to perform high resolution NMR experiments and how to obtain structural and dynamic information on paramagnetic metal ion containing systems.

Giacomo Parigi, born in Borgo San Lorenzo, Italy, on September 17, 1967, graduated in Physics at the University of Florence (1992) and obtained his Ph.D. in chemistry at the University of Florence, Italy. He is Associate Professor of Chemistry since 2006 at the University of Florence. His research interests are mainly oriented to the study of NMR effects related to paramagnetism for the structural and dynamic characterization of biomolecules, to the analysis of the relaxometric profiles of paramagnetic systems and biomolecules, and to nuclear and electron relaxation.

Bertini, Ivano
Ivano Bertini, born on December 6, 1940 in Pisa, Italy, obtained the Italian degree of Doctor of Chemistry at the University of Florence in 1964 and became Full Professor of General and Inorganic Chemistry in 1975 at the University of Florence. A member of the Academia Europaea and the Italian Accademia dei Lincei, he received the Laurea Honoris Causa from the University of Stockholm, Ioannina and Siena. In 1999, he founded the Magnetic Resonance Center (CERM), a major NMR infrastructure in the Life Sciences. His main research interests included advancements in nuclear magnetic resonance spectroscopy, the expression and preparation of metalloproteins, their structural characterization, and the investigation of their interactions, with an emphasis on understanding cellular processes at the molecular level. He published over 650 research articles and solved more than 150 protein structures. He passed away on July 7, 2012.
