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.
