Abstract
A series of ZSM-5 samples with differing framework aluminium contents (containing tetrapropylammonium cations, [TPA] +) have been characterised by Raman spectroscopy. Difference Raman spectra reveal evidence for two distinct occluded species in samples with non-zero framework aluminium content. These species have been identified as [TPA] + cations associated with framework anionic sites and non-framework anions such as Br - or OH -, on the basis of correlations between the integrated intensities of difference spectra and zeolite aluminium content. The relative abundance of the two forms have been determined semi-quantitatively and empirical evidence for [TPA] + disordering is reported.
