“…Today NMR spectroscopy is a complex analysis which includes a number of individual techniques. 26 Since the basis and principles of all NMR techniques are already described in detail in a number of publications, 19,[28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43] only a brief description of the ssNMR technique will be presented here. The ssNMR technique is used to obtain information about the molecular mobility and, consequently, ion conductivity, water and methanol transport properties in different materials, such as protic ionic liquids (ILs) and their nanocomposites, solid proton conductive salts, and polymer electrolytes.…”
