SWS (S01) spectrum of the source RAFGL 7009S between 2.5 and 18 microns (bottom), compared with a laboratory spectrum of a photolysed ice mixture H2O :CO:CH4:NH3:O2 = 10:2:1:1:1 (top).

This spectrum was presented in letter "ISO-SWS observations of solid state features towards RAFGL 7009S", by L. d'Hendecourt et al, that was published in the ISO dedicated issue of Astronomy and Astrophysics Letters.
