Computational Study of the Reaction between Ethylene Glycol and the CH Radical: Competition between Carbon Addition and Dehydrogenation.

ABSTRACT: The gas-phase reaction between ethylene glycol ((CH₂OH)₂) and the methylidyne radical (CH) has been investigated with the aim of understanding the competition between carbon addition and dehydrogenation processes under interstellar conditions. The former type of reaction increases the molecular complexity and leads to the formation of members of the C₃H₆O₂ family (with the hydrogen atom as coproduct), while the latter somewhat decreases the chemical complexity but opens the way toward the gas-phase production of C₂H₄O₂ isomers (together with the CH₃ radical as coproduct). An accurate investigation of the reactive potential energy surface indicates the formation of five isomers belonging to th
