“…Literature precedence also suggests that the skeletal ring structure of cyclic energetic materials is attacked late during the thermochemical decomposition process after the rate-controlling bond rupture occurs [2,3,5,[8][9][10]12,24,25,28,29,41,42,45,46]. Therefore, the consistent decrease in DNNC decomposition rate with increased deuterium substitution in Table 7 cannot be a random occurrence under these documented mechanistic circumstances.…”
