title: NMR spectroscopy: a powerful tool for detecting the conformational features of symmetrical persubstituted mixed cyclomaltoheptaoses (beta-cyclodextrins).
abstract: The conformation in solution of exhaustively derivatized mixed cyclomaltooligosaccharides (cyclodextrins) has been defined by NMR spectroscopy. Both tilting of glucopyranose units about the glycosidic linkages and ring deviations from the 4C1 chair conformation are detected, the entities of which are strongly dependent on the nature of the derivatizing groups.
