Si and ''C NMR spectra of all possible pertrimethylsilylated p-D-xylopyranosyl-substituted methyl 4-0-p-Dxylopyranosyl-p-D-xylopyranosides are assigned by heteronuclear 'H-X 2D NMR chemical shift correlation experiments, where X = C or Si. It is shown that the 29Si NMR spectra can be used for identi
Assignment of the 1H, 13C and 15N NMR spectra of methyl β-D-glucopyranoside tetranitrate, β-cellobiose octanitrate and cellulose trinitrate by two-dimensional homonuclear and heteronuclear 13C1H and 15NOC1H shift correlation spectroscopy

✦ Synopsis
The unambiguous assignment of all the 'H, I3C and "N resonance signals in methyl /h-glucopyranoside tetranitrate and /hellobiow octanitrate was made using homonuclear and heteronuclear * 3C- 1H and"N-O-C-'H two-dimensional shift correlation NMR experiments. Solvent-induced shifts were used to confirm the "C-'H correlations in fl-cellobiose octanitrate. Based on these observations and selective decoupling experiments, the "N resonance signals in cellulose trinitrate were tentatively assigned.
