Methods of high time-resolution spectroscopy were used to determine two stages of explosive luminescence in solid energetic materials: the pre-explosive stage and the stage of processes occurring in explosion products. It was experimentally established that in silver azides the heating of a sample at the end of the pre-explosive stage does not exceed ~ 300 K; while at the second stage the temperature of the explosion products reaches ~ 3000 K. As it follows from the data obtained the major portion (~ 90%) of the energy released during the explosion in AgN 3 is associated with the processes occurring in the explosion products.

Sensitivity prediction is a complex problem. Many studies attempted to correlate experimental data with molecular and microscopic features. In the context of the well-recognized macroscopic hot spot model, an application of an original approach to predict impact sensitivity of 11 explosives is described in terms of parameters of explosive decomposition. This model provides a useful tool in the research for new explosives and the results do not depend on the calculation of solid-state formation enthalpy of explosives.
