Formation of N-bearing complex organic molecules in molecular clouds: Ketenimine, acetonitrile, acetaldimine, and vinylamine via the UV photolysis of C${}_2$H${}_2$ ice

K. -J. Chuang, C. Jäger, J. C. Santos +1

The solid-state C${}_2$H${}_2$ chemistry in interstellar H${}_2$O-rich ice has been proposed to explain astronomically observed complex organic molecules (COMs), including ketene (CH${}_2$…
