title: Application of ultra-high magnetic field for saccharide molecules: 1H NMR spectra of 6-O-alpha-D-glucopyranosyl-cyclomaltoheptaose and -cyclomaltohexaose.
abstract: 1H NMR spectra of G1-alpha-CD and G1-beta-CD were recorded using a spectrometer equipped with a 21.6 T magnet. An ultra-high magnetic field was effective for detecting 1H NMR signals with a small difference in chemical shifts. Introducing a glucosyl group onto CDs as a branch caused deformation of equilibrated 1H signals of cyclodextrin. Particularly, 1H signals in branched glucose were shifted greatly.
