Abstract: We present ISO-SWS observations of the dense part surrounding the protostellar object RAFGL7009S. In this study, we concentrate on simple molecules detected in the gas and ice state (H_2O, CO_2 and CH_4) with the SWS(AOT06). Estimates are derived for their corresponding gas-to-solid ratios and lead to fractions around 0.2 for both H_2$O and CH_4 and almost an order of magnitude lower for CO_2. The gas phase temperature for these species in the gas is dominated by a rather cold component (~50 K). We discuss briefly the possible implications for the chemistry in this region.
