Advances in nuclear magnetic resonance spectroscopy: case of proton conductive materials

“…NMR spectroscopy is one of the most interesting nondestructive/noninvasive techniques that uses the advantage of the nucleus magnetic properties to monitor the material structure and to determine the physicochemical properties of the substance. 26,27 Such a technique has a long history of development starting from the observation of proton wide-line spectra in solution and up to multidimensional experiments in solid-state ( e.g. to provide information about molecular reorientations of NMR active nuclei such as 13 C, 15 N, or 31 P, etc.…”

“…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, 19,28–43 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.…”
