The High‐Pressure Characterization of Melt‐Castable Energetic Materials: 3,3′‐Bis‐Oxadiazole‐5,5′‐Bis‐Methylene Dinitrate
Abstract
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.
