Structural/thermal decomposition relationships are assessed in this project. The relative concentrations of the first observed, infrared‐active gas products generated by fast thermolysis (dT/dt = 110 K/s) of 2,5‐dioxo‐1,3,4,6‐tetranitro‐tetrahydrocyclobutan[1,2‐d : 3,4‐d′]diimidazole (TDCD) and 1,3,4,6‐tetranitroglycoluril (TNGU) were successfully predictable from structure/thermal decomposition relationships. The predictions for 1,4‐dinitroglycoluril (DINGU) were only partly successful. The departures from expection appear to originate from the different degree of stability of the non‐energetic backbone of these molecules. The dependence of the first‐observed gas products on pressure from these molecules was qualitatively predicted from the nature of the products liberated at atmospheric pressure.
