Readers will discover the exciting world of NOE (nuclear Overhauser effect), RDC (residual dipolar coupling) and J-coupling constants, both short- and long range. With emphasis on obtaining structural knowledge from these NMR observables, focus is moved from solving a static 3D structure to solving the structural space inhabited by small organic molecules. The book outlines the development and implementation of two Heteronuclear Multiple Bond Correlation-type NMR experiments, and the 3D structural elucidation of multiple known and novel compounds. In addition, a new method of back-calculating RDCs (allowing for more flexible structures to be investigated), and the synthesis and evaluation of novel chiral alignment media for ab initio determination of absolute stereochemistry of small molecules using RDCs are also included. Challenges that 3D structural generation of small compounds face are also covered in this workSummary: NMR spectroscopy: Past to present -- Theory - 3D structural information from NMR, part 1 -- Application of NOEs and 3JHH-couplings in 3D structure determination -- Development of NMR experiments for determination of long-range J-coupling constants -- Theory - 3D structural information from NMR, part 2 -- Determination of long-range residual dipolar coupling constants -- Chiral alignment media for enantiodiscrimination -- Tensor free RDC calculations -- Overall perspective and conclusionsPPN: PPN: 1040278620Package identifier: Produktsigel: ZDB-2-CMS | ZDB-2-SEB | ZDB-2-SXC
