Abstract: In situ MAS NMR spectroscopy under continuous-flow conditions and spin-echo NMR experiments is applied to investigate the quadrupolar interactions of framework aluminum atoms in zeolite H-ZSM-5 at elevated temperatures and during conversion of methanol. The study can be explained by jumps of the hydroxyl protons between two or three of the energetically favored oxygen atoms of each aluminum site or between different aluminum sites.
