13C NMR spectra of undoped polyacetylene, (CH),, have been measured. The existence of 3.4 mol% methyiene moieties as defects in the (CH), chains has been observed in t~ans-(CH)~. Measurements of partially cis-to-trans isomerized (CH), suggest the existence of isolated cis regions.

## 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
