Description

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.

Readership

For graduate students of chemistry, biochemistry and biophysics, moreover, chemists, biochemists, inorganic chemists, researchers interested in Spectroscopy and NMR who will encounter paramagnetic molecules in their research as a common event and will discover that the techniques here described are fundamental for their investigations. Teachers of graduate courses in biophysics and advanced inorganic chemistry may find part of the book suitable for the students.

Ivano Bertini

Ivano Bertini was born on December 6, 1940, in Pisa, Italy. He gained his Ph.D. at the University of Florence, Italy, in 1964 and the Libera Docenza in 1969. He became Full Professor of General and Inorganic Chemistry in 1975 at the University of Florence. In 1999, he founded the Magnetic Resonance Center (CERM) at the University of Florence, a major NMR infrastructure in the Life Sciences. Bertini's research focused on the structure-function relationship of metalloproteins, explored with biophysical methods. He is particularly known for using NMR spectroscopy and for pioneering the exploitation of genome data banks, most recently to identify pharmaceutical targets. He pursued advancements in technology for solution structure determination, particularly for paramagnetic metalloproteins, and developed specific software applications. Bertini published over 650 research articles and has solved more than 150 protein structures. He was also on the editorial staff or advisory board of over 20 journals in chemistry, biochemistry, and inorganic chemistry, including ChemBioChem, ChemMedChem, and the European Journal of Inorganic Chemistry Bertini passed away in 2012 while still fully scientifically active.
