Abstract

In the rapidly growing field of metabolomics, a comprehensive book describing the state of the art in the application of NMR spectroscopy will be a key title for practitioners. Providing a unique resource of background knowledge, resources, instrumental platforms and software, this book will introduce relevant theory to the researcher as well as serve as a practical guide detailing key experiments and data handling procedures. Information available on common sample types will be described together with reference to the latest web-based resources available. Application-specific considerations will be discussed for a wide range of research topics. Written by an expert team as a service to the metabolomics community, this book will appeal to NMR spectroscopists, analytical chemists and biochemists especially those with an interest in medical applications.
