Fragmentation Dynamics of Energetic Materials.

Abstract

A molecular beam unimolecular fragmentation mass spectrometer has been developed and applied to the study of primary dissociation processes in energetic materials. The experimental approach uses infrared multiphoton excitation to prepare isolated molecules in the beam for dissociation. Visible laser induced multiphoton ionization detects products with time-of-flight scattering angle and internal quantum state resolution. This report describes the method, spectroscopic results on CH2, CH3CHO, sym-C3N3H3 and NO2, together with experimental observations on the primary decomposition dynamics of NO2, and RCHCH2O with R = CH3, C2H5, and C6H13. Keywords: Energetic materials; Unimolecular decomposition; Primary reactions; Nitro paraffins; Nitramines; Alkyl epoxides; Molecular beams; Infrared multiphoton dissociation; MPI (Multiphoton Ionization).
