Description	27Al 3Q MAS NMR spectroscopy and DFT/MM calculations were employed to study the Al siting in eleven differently synthesized samples of the ZSM-5 zeolite. The results of our study reveal that the occupation of the distinguishable framework T sites by Al and the concentration of Al in these T sites are neither random nor controlled by a simple rule. They both depend on the conditions of the zeolite synthesis. We further found that at least 10 out of the 24 distinguishable framework T sites are occupied by Al in our ZSM-5 samples. 27Al 3Q MAS NMR spectroscopy and DFT/MM calculations were employed to study the Al siting in eleven differently synthesized samples of the ZSM-5 zeolite.
