Report of results of research on the initial stage of detonation is made. Experimental results involve location of a heretofore undetected intramolecular mode in RDX and confirmation of prior findings on the Raman scattering of HMX. Preliminary Brillouin scattering studies have permitted experimental determination of approximate values of all components of the HMX crystals stiffness tensor. The results of a mechanochemical theory are presented. The model account for the initial stage of detonation involving molecular decomposition. Symmetry arguments based on the theory show that high symmetry molecules will be inherently less stable under compression than higher symmetry ones. The mechanochemical model also offers a direct explanation of the role of hot spots in detonation.
