In this work we assess the viability of the CH 2 CH 2 +OH gas phase exothermic route as a mechanism for the formation of formaldehyde and acetaldehyde in the Interstellar Medium. The relevant features of the potential energy surface of the system have been characterized by accurate quantum chemical calculations, identifying the available pathways as a sequence of minimum and transition state structures, with no entry barriers. Preliminary theoretical kinetics calculations have been performed at the low temperature range characteristic of the spatial environments where such neutral-neutral reactions could be of interest.

Abstract
In this work we assess the viability of the CH 2 CH 2 +OH gas phase exothermic route as a mechanism for the formation of formaldehyde and acetaldehyde in the Interstellar Medium. The relevant features of the potential energy surface of the system have been characterized by accurate quantum chemical calculations, identifying the available pathways as a sequence of minimum and transition state structures, with no entry barriers. Preliminary theoretical kinetics calculations have been performed at the low temperature range characteristic of the spatial environments where such neutral-neutral reactions could be of interest.File in questo prodotto:
