The High-Pressure Characterization of Melt-Castable Energetic Materials: 3,3 '-Bis-Oxadiazole-5,5 '-Bis-Methylene Dinitrate
The high-pressure behavior of 3,3 '-bis-oxadiazole-5,5 '-bis-methylene dinitrate (BODN) was studied at room temperature to 25 GPa by Raman spectroscopy and powder X-ray diffraction. The Raman spectra, powder patterns, and calculated unit-cell volumes at selected pressures show qualitative agreement with first-principles density function theory calculations. Over this pressure range, no evidence of polymorphism was observed which suggests that this energetic material can be formulated without the concern of forming lower-density phases at elevated pressures. Vibrational measurements suggest a reversible deformation of the C-C linkage between the oxadiazole rings with increased pressure.
