Resumen: | Formamide has a key role in prebiotic chemistry as it is the simplest molecule containing the four most important atoms from a biological point of view: hydrogen, carbon, nitrogen and oxygen. Due to its importance, the formation of this molecule has been studied and different pathways have been considered both in gas-phase and on ices of dust grains since it was first detected. In the present work, the thermodynamics of the formation route of formamide starting from NH2 and H2CO, a reaction channel proposed to occur in the gas phase, has been theoretically investigated in the scenario taking place on icy dust grains modelled by both a cluster and a periodic approach. Different DFT functionals have been employed to obtain accurate energy values for the mechanistic steps involved in the reaction. |
