Abstract

We report what is believed to be the first measurements of dielectric properties in the terahertz frequency range of different types of water molecules existing in the bulk, structural or interfacing forms in the nanostructured alumina oxyhydroxide (NAO). We show that the dielectric permittivity associated with these kinds of water molecules differ from that of liquid bulk water.
