Solid poly[(R)-3-hydroxybutyric] acid was examined by high-resolution 13C MAS NMR, differential scanning calorimetry and infrared spectroscopy. The 13C methyl group resonance consists of three components: the rigid amorphous phase, the crystalline phase and the mobile amorphous phase. Spectral decon
## Abstract Scleroglucan is a branched poiysaccharide, soluble in water. Solidβstate and solution ^13^C NMR were used to follow the fixation of water molecules on anhydrous scleroglucan and the evolution of the scleroglucanβwater complex from the solid state to the gel and solution state. Determina
