The general development of Rheo-NMR during the last four decades as well as selective hyphenated apparatuses is presented. Based on different magnet types, the current review is divided into two categories, namely low-field and high-field NMR, while the time-domain NMR is normally applied in the former case and the frequency-domain NMR is adopted in the latter one. Depending on different rheometer cells, it can be further divided into tensile and shear mode Rheo-NMR. The combination of various rheometer cells and NMR facility guarantees our acquisition of molecular level structure and dynamics information under flow conditions, which is crucial for our understanding of the molecular origin of complex fluids. A personal perspective is also presented at last to highlight possible development in this direction.
