Observation of the fundamental bending vibrations of hydroxyl groups in HNa$z.sbnd;Y zeolite by neutron inelastic scattering*1

This article reviews recently published work showing how inelastic neutron scattering spectroscopy can be used to identify species found in zeolite ZSM-5 used as a catalyst for conversion of methanol to hydrocarbons. The advantages and disadvantages of the technique are illustrated, and current challenges identified.
