Unimolecular dissociation of doubly ionized toluene and electron transfer between neutral toluene and its dication
2012
Abstract
Dissociative double ionization of toluene using synchrotron radiation in conjunction with theoretical studies leads to a determination of the thermochemistry of the dication c-C7H62+. Further, photon-energy dependent reactivity studies reveal that the asymmetric energy deposition upon single-electron transfer in the C7H82+/C7D8 collision system is not influenced by the internal energy content of the dication precursors.
This finding agrees with the previous assignment of the asymmetric energy deposition as a consequence of the electronic states accessible upon recombination of a dication with an electron compared to the removal of an electron from a neutral compound, respectively.
