This book describes advanced developments in the methodology and applications of NMR spectroscopy in the life science and materials science fields. In this book, new experimental methods and new NMR research fields are presented with chapters on the structure of membrane proteins, in cell NMR, and Electro-Mechano-Optical NMR is added. Experts in the field have contributed an exciting range of topics that cover recent advances in high-pressure NMR, selectively isotope-aided NMR, ultrafast MAS NMR, dynamic nuclear polarization (DNP) NMR, optical and microwave irradiation NMR. This book emphasizes the experimental details for new researchers to use NMR spectroscopy and pick up the potentials of this technique. It is also designed for those who are involved in either developing the technique or expanding the NMR application field by applying them to specific samples. The Nuclear Magnetic Resonance Society of Japan has organized this book not only for NMR users of Japan but also for readers worldwide who are interested in using NMR spectroscopy extensively.
