【 摘 要 】

The use of Nuclear Magnetic Resonance spectroscopyto establish the three-dimensional structures of molecules is an important componentof modern Chemistry courses. The combination of techniques that can be usedfor this purpose is conveniently illustrated by their application to the camphormolecule. This paper presents applications of several techniques used in NMRspectral interpretation in an increasing order of complexity. The result ofindividual experiments is illustrated in order to familiarize the user withthe way connectivity through bonds and through space is established from 1D/2D-NMRspectra and molecular stereochemistry is determined from different NMR experiments.
