16 Thermally Enhanced Fourier-Transform Infrared Spectroscopy (TE-FTIR) is a new method 17 applied to examination of thermal stability of energetic materials. Three melt-cast explosives: 18 2,4,6-trinitrotoluene (TNT); 2,4-dinitroanisole (DNAN) and propylnitroguanidine (PrNQ) were 19 selected for testing. The obtained results revealed new facts about the stability of tested 20 explosives and explosives in general. They clearly showed that PrNQ was subject to 21 decomposition in a violent manner
