Solid-state deuterium nuclear magnetic resonance of the methyl dynamics of poly(α-methylstyrene) and polymethylphenylsilane
2000
Journal of Chemical Physics
The methyl-d 3 dynamics of two relatively similar polymers, poly͑␣-methylstyrene͒ (PAMS-d 3 ) and polymethylphenylsilane , are investigated via deuterium NMR relaxation experiments. Our analysis of the relaxation data uses the entire solid-echo spectra to maximize the precision of the experiments with regard to the information available on the methyl dynamics. The analysis is novel in that it does not use M ϱ or M 0 to fit the relaxation data. Additionally, the three-site symmetric jump model
