Roaming Reactions and Roaming-Mediated Isomerization in the Decomposition of Energetic Materials.

摘要

In the course of this project, roaming reactions and roaming-mediated isomerization were studied in a range of nitro compounds. To this end, infrared multi photon dissociation was coupled to state-resolved velocity map imaging for the first time. Systems studied in detail included nitromethane, nitroethane, 1-nitropropane and nitrobutane, as well as the corresponding nitrites. In addition, these same techniques were applied to vinyl chloride dissociation, where state-resolved imaging clearly showed the ground state dissociation at threshold proceeds by 3- center elimination to give the elusive vinylidene reaction intermediate as a product.
