Dynamics of Highly Energetic Azabenzenes

Abstract

Competition between unimolecular decomposition of highly energetic azabenzene molecules and relaxation via collisions with bath molecules is investigated to provide insight to the dynamics of prototypical explosive materials. High energy azabenzene molecules (4-5 eV) are prepared with pulsed tunable UV excitation and the resulting energy loss processes are monitored using high resolution transient infrared absorption spectroscopy. Nascent energy gain measurements in bath molecules such as CO2 and H2O provide information about the energy transfer partitioning, cross sections and distribution functions. Computer simulations using classical trajectory calculations help identify the molecular features that lead to efficient (or inefficient) energy loss pathways.
