Decomposition of Energetic Materials from Excited Electronic States - RDX, HMX, Model Nitramines

Abstract

The energetic materials RDX, HMX, and CL-20 are studied in the gas phase by mass spectroscopy, optical wavelength resolved and time resolved spectroscopic techniques. We learn that NO is the first product of the dissociation of these molecules excited to their first electronic excited singlet states. The NO appears at less than 100 fs following the excitation pulse. A number of cyclic and non cyclic nitramine model systems are studied in parallel with the energetic materials and, which NO is their first decomposition product from their excited electronic states, it appears with a very different internal energy distribution. We suggest a number of possible general ideas for improving the energy yield from energetic materials.
