Triplet State Dynamic Nuclear Polarization: Basics, Concepts, Methods Kazuyuki Takeda

Over the last several years, the use of nuclearhyperpolarization techniques in nuclear magneticresonance (NMR) spectroscopy and magnetic resonanceimaging (MRI) has increased exponentially. Since thesignal sensitivity can be enhanced by orders ofmagnitude compared to that in the normal conditions, nuclear hyperpolarization, when applied to NMR/MRIstudies of chemical/biological interest, could enableus to observe what we have so far not been able to, and thereby bring us into a new realm of science. This book focuses one of several ways to attainnuclear hyperpolarization, namely, dynamic nuclearpolarization (DNP) using electron spins in thephoto-excited triplet state, addressing its basicprinciples, discussing the elementary processes ofspin-polarization transportation behind the buildupbehavior, and presenting practical experimental tips. Thus, this book should be especially useful tograduate students in physics and chemistry studyingnuclear hyperpolarization, and anyone who may beconsidering utilizing nuclear hyperpolarization forNMR/MRI in chemical, biological, and medical sciences.
