Abstract

The VLT has opened up the possibility to perform spectroscopic surveys of large number s of young low-mass stars which are still deeply embedded in their parental clouds. O ur infrared spectra show a rich variety of features due to ices and gas-phase molecule s, each of which trace different aspects of the physical and chemical state of the obj ects. Highlights include fundamental new insight into the structure of interstellar i ces; the first detection of solid methanol in low-mass protostars, a key ingredient fo r building more complex organic molecules; direct evidence for significant freeze-out in edge-on circumstellar discs; and sensitive limits on minor ice components such as a mmonia and deuterated water.
