It has been predicted by theoretical models that ethane and ethanol are present in icy mantles covering dust particles in dense interstellar clouds. Laboratory spectra of ethanol embedded in astrophysically relevant ice matrices were compared to the

We use Fourier transform infrared (FTIR) reflection spectroscopy (incidence angle of 5°) to characterize thin films of ethylene oxide (EO) and water/EO mixtures (between 11 and 170 K under a pressure of 10 −7 mbar). The photochemistry of EO in mat

Dimethyl-ether has been identified in the interstellar gas in cold molecular clouds. It is therefore most probable that it can be trapped in the mantles of low temperature interstellar grains. Laboratory studies have been performed in order to simula

This paper focuses on systematic examination of the vibrational frequency shifts of some molecules trapped in water ices. It is shown that for the bands, for which the laboratory taken data are available, the magnitude and the sign of a vibrational s

FTIR spectra of solid ClNO 2 in interaction or not with amorphous water ice between 11 and 200 K were analyzed, and the photochemistry of these solids was investigated. When ClNO 2 is deposited on an ice surface at 30 K or trapped in the water lattic
