摘要：

Neutron inelastic scattering has been used to study the adsorption of water, at low loading, in zeolite H-mordenite. The results are compared to the neutron spectra of the bare zeolite and of ice. For the bare zeolite, the in-plane and out-of-plane bending modes of the bridged hydroxyl groups are measured at 1060 and 320 cm-1, respectively. After water adsorption, the observed vibrational features are assigned to different species: hydroxonium ions, H2O hydrogen bonded, and free hydroxyl groups.
