NMR has become truly a multidisciplinary area of science dealing with applications ranging from basic to applied sciences including medical, agricultural and industrial. In addition to being an indispensable tool in chemical sciences, NMR is now recognized as an important field in biomolecular structural studies as well as medical diagnosis and intervention. The exciting developments in NMR are still continuing and it is hoped that the day may come when pocket size NMR spectrometers for specific applications may become available. It is therefore, appropriate to bring out a book on this exciting subject with contributions from world renowned experts in the respective areas. The present book contains articles on applications of NMR to metabonomics, early diagnosis of diseases, protein structure determination, NMR in liquid crystals, technique developments, sub-compact NMR instruments and quantum computing.
