N2 - The vibrational density of states (VDOS) for water confined on the surface of rutile-Ti0 2 nanoparticles has been extracted from low temperature inelastic neutron scattering spectra. Two rutile-Ti0 2 nanoparticle samples that differ in their respective levels of hydration, namely TiO 2•0.37H 2O (1) and TiO 2•0.22H 2O (2) have been studied. The temperature dependency of the heat capacities for the two samples has been quantified from the VDOS. The results from this study are compared with previously reported data for water confined on anatase- TiO 2 nanoparticles.
