An Isotope-labeling Study of CO2 Formation Pathways in Molecular Clouds: Ultraviolet Photolysis of CO–H2O Ice
With the use of reflection–absorption infrared spectroscopy, we investigated the binary ice of CO and H _2 O at 10 K under ultraviolet irradiation as an analog of the interstellar ice mantle. We employed H _2 ^18 O instead of H _2 ^16 O to distinguish the formation pathways of CO _2 , and prepared m...
