Abstract: We report absorption features of solid CO2 stretching and bending modes in several lines of sight, including embedded young stellar objects and the Galactic Center source Sgr A*. The overall CO2 abundance in ices is similar to 15% relative to H2O. Profile shapes are consistent with the presence of grain mantles with distinct polar (H2O-rich) and nonpolar (CO or CO2-rich) layers. In addition to the normal isotopic form, we report detection of the stretching mode of (CO2)-C-13; the C-12/C-13 ratio is consistent with terrestrial and interstellar values.
