Neutron spectroscopy of water adsorbed on silica

Computational and real neutron scattering experiments are presented. The computations were performed in a modern cluster approximation, which is used in computational chemistry. The amplitude-weighted densities of the vibrational states for a few models of the water molecule depositions at the surface are obtained. The results are in good agreement with the experimental inelastic neutron scattering spectra. © 1991.
