The Deuteron NMR Hahn Echo Decay in Polyethylene oxide melts

Description

Presentation of 2H NMR Hahn Echo decays in deuterated polyethylene oxide melts for four different molecular weights between 3.5 kg/mol and 300 kg/mol. The results are compared to predictions based on the Rouse and reptation formalisms, considering the dynamical heterogeneity of linear polymer chains produced by their end segments.
