Bromonitromethane (CH[SUB2]BrNO[SUB2])(BrNM) is chemically similar to nitromethane (NM), with one hydrogen atom replaced by bromine. It is a liquid explosive with an initial density of 2.009 g/cm[SUP3]. We have shown its sensitivity to shock to be similar to neat NM. Its von Neumann spike pressure is calculated to be nearly twice that of NM while the CJ pressure appears to be only slightly higher than NM. The sound speed of BrNM was measured to be 1.16 km/s and was used in the Universal Liquid Hugoniot (1). Shock Hugoniot measurements were shown to be consistent with this prediction. In addition, we report the results of failure diameter measurements, and the diameter effect curve in brass confinement. Detonation wave profiles obtained using VISARs that record the interface particle velocity between detonating BrNM and a poly(methyl methacrylate) window are also reported.

    Liquid nitromethane (CH[SUB3]NO[SUB2] -- NM) is an important explosive material because of its chemical and physical simplicity. It has proved useful in studies of the chemistry and physics of initiation and detonation. We have experimentally investigated some of the effects on its properties...

    It has been shown that the temperature of explosively generated plasma (EGP) is of the order of 1 eV and plasma ejecta can be focused to achieve velocities as high as 25 km/s. Proof-of-principle tests were performed to determine if EGP could be used for explosive ordnance demolition and other...

    Atomistic mechanisms underlying the reaction time and intermediate reaction products of detonating high explosives far from equilibrium have been elusive. This is because detonation is one of the hardest multiscale physics problems, in which diverse length and time scales play important roles....
