Abstract

Inclusion compounds made of a water ice network, clathrate hydrates, are investigated by infrared spectroscopy. Because they can trap important “guest” volatiles species, they may influence the equilibrium, exchange and flux of volatiles in many bodies of the solar system. Their spectroscopic behaviour at low temperature (10–200 K) are shown and the search for their signatures by comparison to solar system objects remote spectra are discussed.
