Rainer Kimmich is an emerited professor of physics at the University of Ulm. The subject of the proposed book, Field-Cycling NMR Relaxometry, is the research methodology he has been working on over four decades starting in the seminal stages of the technique. A large part of the roughly 300 papers he has authored or co-authored refer to this technology and its applications. He has published two monographs including chapters on this variant of NMR relaxometry.
