Infrared Studies of the SO2 Clathrate Hydrate

This is the authors' abstract. We don't add key points for this paper.

Using infrared spectroscopy, transitions among ice, solution, and clathrate phases are compared with the predictions of the SO 2 −H 2 O phase diagram in the temperature range −20 to 10 °C and SO 2 pressures from 50 to 900 mbar. The infrared signatures of clathrate and ice, as well as SO 2 in a variety of phases are recorded and interpreted in terms of their environments. The consequences of SO 2 in confined geometries within ice are explored.
