NMR Hahn echo decays in deuterated polyethylene oxide melts

This dataset contains the raw and processed ²H NMR relaxation data from Hahn echo (HE) and inversion recovery (IR) experiments in deuterated polyethylene oxide melts of different molar masses (3.5kDa, 33kDa, 75kDa and 300kDa) at different temperatures (55/60°C, 70°C, 85°C and 100°C). The PEO-d₄ samples were placed in 3mm outer diameter NMR glass tubes, covered with Argon and flame sealed. The measurements were performed on a Bruker Avance III NMR spectrometer at a ²H resonance frequency of 46.1 MHz. In addition, matlab scripts to extract the effective transverse relaxation time and to calculate the decay predicted by the Rouse and tube-reptation model taking the effects of dynamical heterogeneity into account (see 10.1063/5.0099293) are included in this dataset.
