Abstract
The interpretation of 220- and 300-MHz P.M.R. spectra and the accurate chemical shifts and coupling constants of a number of per-O-trimethylsilyl-(TMS-)D -fructose derivatives and TMS-oligosaccharides containing beta-D-fructofuranose residues are presented. On the basis of calculations with an adapted Karplus equation it is concluded that TMS-alpha- and -beta-D-fructopyranose occur in the
