This book describes advanced developments in the methodology and applications of NMR spectroscopy in the life science and materials science fields. In this book, experts in the NMR field have contributed an exciting range of topics that cover recent advances in structural and dynamic aspects of material molecules such as silk fibrils, polymer materials and organic light-emitting diodes, and biological molecules such as natural products, glycoproteins, and ribonucleic acid (RNA). This book emphasizes the experimental details for new researchers to use NMR spectroscopy and pick up the potential 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 members of Japan but also for readers worldwide who are interested in using NMR spectroscopy extensively.
