- •
13C-enriched cellulose II was analyzed by solid-state 2D NMR spectroscopy.
- •
Four conformationally different anhydroglucose units were observed for cellulose II.
- •
Two were assigned to crystalline parts, two were assigned to non-crystalline parts.
- •
Spectral deconvolution of C1, C4, and C6 regions of cellulose II were accomplished.
