    Notes: 17O-NMR spectroscopy has found limited application as a structural probe due to the experimental problems associated with a quadrupolar nucleus having low natural abundance. A survey of data obtained from systematic studies of structurally related compounds shows, however, that large chemical shift differences are usually obtained for structurally nonequivalent nuclei, and that characteristic chemical shift values are observed for specific chemical environments. The present day availability of 17O enriched materials and Fourier transform NMR instrumentation should allow extensive application of the 17O-NMR technique to structural problems in the immediate future.

    Notes: Die NMR-Spektroskopie des Isotops 17O, eines Quadrupolkerns mit geringer natürlicher Häufigkeit, wurde bisher wegen experimenteller Schwierigkeiten nur beschränkt zur Lösung chemischer Probleme herangezogen. Ein Vergleich der aus systematischen Studien strukturell verwandter Verbindungen erhaltenen Daten zeigt jedoch, daß nichtäquivalente Sauerstoffatome für gewöhnlich große Unterschiede in den chemischen Verschiebungen aufweisen und daß für 17O in spezifischen chemischen Umgebungen charakteristische Werte der chemischen Verschiebung beobachtet werden. Die gegenwärtige Verfügbarkeit von 17O-angereichertem Material und von Fourier-Transform-NMR-Geräten läßt für die nahe Zukunft eine ausgiebige Anwendung der 17O-NMR-Technik zur Lösung struktureller Probleme erwarten.
