Autor: Zbiegniew Olejniczak, Zeev Luz, Raphy Poupko, Guenter Hempel, Piotr Tekely, Detlef Reichert

Publikováno v: Solid State Nuclear Magnetic Resonance. 13:137-148

One- (1-D) and two-dimensional (2-D) carbon-13 NMR exchange measurements in powder samples of isotopically normal durene under magic angle spinning (MAS) are reported. The experiments include rotor synchronized 2-D exchange (RS2DE), 1-D magnetization

Solid-state spin–lattice relaxation in the rotating frame permits the investigation of dynamic processes with correlation times in the range of microseconds. The relaxation process in organic solids is driven by the fluctuation of the local magneti
