Abstract

Introduction: Laboratory simulations can benefit ground- and space-based observations of icy bodies in outer space. It is well-known that NH₃ and CO₂ can interact, forming ammonium carbamate (CH₆N₂O₂).
Method: This study examines NH₃ and CO₂ in thermally processed H₂O-rich ices in the laboratory via mid-infrared absorption spectroscopy. In particular, the presence of CO₂ in NH₃-ice mixtures thermally annealed at 150 K for more than four hours in systematic experiments suggested that ammonium carbamate could potentially trap volatiles within the ice matrix.
Result: Additional studies with acetonitrile (C₂H₃N) in ice mixtures containing H₂O, CO₂, and NH₃ were also performed. Absorption peak position changes were recorded when the temperature was slowly increased (≤ 5K/min) and also annealed at temperatures up to 150 K.
Conclusion: These studies will hopefully be useful in interpreting pre-biotic chemistry in the Solar System.
Keywords: Astrochemistry, ices, IR absorption spectroscopy, laboratory astrophysics, acetonitrile, solar system.
