Time-domain NMR is a well known tool for assessing the molecular dynamics in soft matter by measuring the excitation and subsequent decay of 1H nuclear magnetization. It is widely used, e.g., to quantify the composition of heterogeneous soft matter systems like semicrystalline polymers or emulsions. Further applications, known from academic research and industrial application, include measuring the moisture content in solids, the residual magnetic dipolar coupling for quantifying molecular motion in crosslinked systems, or diffusometry. We report the integration of a permanent magnet based pulsed NMR spectrometer into a modern, commercially available high-end shear rheometer. The setup allows for the first time to simultaneously conduct time-domain 1H NMR and steady shear or dynamic rheological measurements on one sample and to directly correlate the results from both, without concerns about differences in the sample history or temperature calibration. Moreover, the new in-situ combination allows the full...
