Characterizations of fluorine-superconductors and selected fluorine -compounds, vanadium oxydiphosphate by fluorine-19, carbon-13, proton, phosphorus-31 NMR and a new probe for multiple pulse, MAS and DAS NMR

;Amorphous carbon has been studied by ;The temperature dependence of the chemical shift of ;A stable rotor-stator system is designed that is suitable for NMR experiments of homonuclear decoupling, magic angle spinning, and dynamic angle spinning experiments. A maximum speed of 16 KHz is achieved. The angle of rotation can be changed by 45...
