The TNU‐9 zeolite of the TUN framework is one of the most complex zeolites known. Here, a newly developed approach, which includes 29 Si and 27 Al (3Q) MAS NMR spectroscopy, Co II cations as probes monitored by UV/Vis and FTIR spectroscopies, and extensive periodic DFT calculations including molecular dynamics, is presented for the investigation of the Al distribution and the location of Al pairs and divalent cations in extra‐framework cationic positions in TNU‐9. The α (blue) and β (red) cationic sites for bare divalent cations are suggested. More information can be found in the Full Paper by S. Sklenak et al. on page 8857.
