This book contains three sections covering theory, acquisition, processing and analysis of NMR data, and applications of projection NMR. The first section reviews how methodology and theory of projection NMR evolved since the 1970s; the second section serves as a guide for researchers in the field to become acquainted with the practical aspects of projection NMR, and will provide all information on how to acquire, process and analyze projection NMR data; and, the last section covers current applications, primarily in structural biology and metabonomics. Future developments and perspectives in projection NMR are also discussed thoroughly.
