2. Experimental

Interstellar ices are simulated using low temperature and vacuum techniques in combination with infrared spectroscopy. Ices are condensed as pure gases or gas mixtures onto the surface of a CsI window in a high vacuum chamber and cooled by a closed-cycle He refrigerator to 10 K. Infrared transmission spectra were obtained with a BioRad FTS 40A (Leiden) and a Brucker FTS IFS 66v (Paris) spectrometer at a resolution of 1 cm^-1.
