The transport of a proton through hydrogen bonds plays a crucially important role in environments related to acid/base chemistry, biochemistry, and atmospheric chemistry. (1−5) Water ice has long been studied to understand the transfer of a proton through chains of hydrogen bonds. The unique electrochemical property of water ice, resembling a “p-type semiconductor”, has been characterized by the Grotthuss mechanism, (1,6) which demonstrates that excess protons are relayed along hydrogen bonds.

AbstractMany interstellar complex organic molecules (COMs) are believed to be produced on the surfaces of icy grains at low temperatures. Atomic carbon is considered responsible for the skeletal evolution processes, such as C–C bond formation, via insertion or addition reactions.
