Abstract
Water ice is the most important component in astrophysical ices and is characterized by a strong broad absorption at 3 µm, observed in many interstellar spectra. In specific interstellar environments grain mantles might contain only a small amount of water, which is diluted in other volatiles dominant in these regions (e.g. CO, O2, N2, CO2). Isolated water molecules display very sharp discrete bands between 2.5 and 2.9 µm, shortward of the 3 µm polymeric H2O ice band. We have performed a detailed study of the infrared properties of H2O diluted in various matrices and discuss the possible detection of isolated water on low temperature and ultraviolet shielded grain mantles covered with non-polar ices. Together with astronomical spectra taken by the ISO satellite these laboratory data will be extremely valuable for the determination of the grain mantle composition in dense clouds.
