Abstract

In this article, I have presented quantum mechanical treatment of methanol formation reaction from methane water-ice cluster after ionization with high energy photons. To mimic water ice structure, six water molecules are arranged in hexagonal form. This is the most stable structure formed by six water molecules. Theoretical photodesorption study has been performed on this structure. I have investigated a unique reaction mechanism of methanol formation from methane water ice cluster. I have shown that methanol forms after ionization via two transition states. Hydrogen molecule forms as one of the side product. Initiation of the reaction occurs by dissociation of OsbndH bond in the water cluster followed by CsbndH bond dissociation and formation of CsbndO bond. The timescale of the initial step, which is dissociation of OsbndH bond, has been computed as 50 femtosecond in this article. © 2019 Elsevier B.V.
