Graphical Abstract

Die Rotationsdynamiken von Benzolringen im flexiblen MIL-53- und im starren MIL-47-Gerüst wurden durch 2H-NMR-Spektroskopie untersucht. In beiden Fällen werden 180°-Flips beobachtet, wobei der Flip-Prozess in MIL-53 schneller ist. Zur Simulation der experimentellen Spektren (links) reicht die Berücksichtigung der quadrupolaren Wechselwirkung nicht aus (Mitte): Auch der paramagnetische Effekt muss einbezogen werden (rechts).
