Abstract:Explaining the formation pathways of amides on icegrain mantels is crucial to understanding the prebiotic chemistry in an interstellar medium. In this computational study, we explore different radical-neutral formation pathways for some of the observed amides (formamide, acetamide, urea, and N-methylformamide) via intermediate carbamoyl (NH 2 CO) radical precursors and their isomers. We assess the relative energy of four NH 2 CO isomers in the gas phase and evaluate their binding energy on small water clusters… Show more
