Proton-transport catalysis and proton-abstraction reactions: An ab initio dynamical study of X+HOC+ and XH++CO (X=Ne, Ar, and Kr)

Abstract

Ab initio potential energy surfaces have been constructed and used to carry out classical simulations of the reactions of X with HOC+ and of XH+ with CO (X=Ne, Ar, and Kr). The competition between rearrangement, X+HOC+→OCH++X, and abstraction, X+HOC+→XH++CO, has been examined, and found to favor abstraction in the cases where both processes are energetically allowed. The reaction of XH+ with CO is found to produce highly vibrationally excited [CHO]+ products.
