title: Terahertz time-domain spectroscopy of submonolayer water adsorption in hydrophilic silica aerogel.
abstract: We report a terahertz time-domain spectroscopy study of the adsorption of water in hydrophilic silica aerogel. The adsorbed water is in submonolayer form and shows properties of index of refraction similar to those of bulk water but different absorption properties.
