Photoionization of methanol: a molecular source for the prebiotic chemistry

Abstract

Methanol is one of the most abundant and ubiquitous molecules in the space. Its chemistry is fundamental to understand the molecular growing from prebiotic molecules, ions and radicals. In this work the reaction of labelled methanol CD3OH•+ radical cation, produced with different internal energies by monochromatic synchrotron radiation, with neutral CD3OH was studied. The dynamics of the main reaction channels were investigated by theoretical calculations. The results show how these processes can be considered suitable pathways for the formation of fundamental species as CH3O(H)H+, CH3O•, •CH2OH, CH2O which are potential precursors to prebiotic molecules.
