Solid-state 13C CP/MAS NMR spectra are reported for di †erent EDTA-metal complexes. The e †ect of metal binding on the isotropic 13C chemical shift and principal elements of the carboxyl 13C chemical shift anisotropy (CSA) tensor are discussed.
## Abstract Scleroglucan is a branched poiysaccharide, soluble in water. Solid‐state and solution ^13^C NMR were used to follow the fixation of water molecules on anhydrous scleroglucan and the evolution of the scleroglucan—water complex from the solid state to the gel and solution state. Determina
## Abstract In order to obtain some insight into the structure of an ultrahigh‐molecular‐weight polyethylene sample, ^13^C CP/MAS NMR experiments have been carried out at temperatures from 23 to −108°C. The peak for the crystalline component moves upfield with a decrease in temperature, which is co
## Abstract The carbon‐13 spin‐lattice relaxation times __T__~1~ of the crystalline components of four solid ethylene‐octene copolymers have been studied as a function of thermal history, branching number, and branching distribution. Slowly cooled samples (1 deg/min from melt to room temperature) e
