Abstract The nitramines ε- and β-2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitanes (ε-CL-20 β-CL-20), cis-1,3,4,6-tetranitrooctahydroimidazo-[4,5-d]imidazole (BCHMX), six β-CL20/BCHMX co-agglomerates (CACs) 1,3,5-trinitro-1,3,5-triazepane (TTAZ) have been subjected to XPS analysis determine their N 1s (N-NO 2 ) O (NO binding energies ( E bind ). values for found be closely related the molecular structure of studied; growth logically corresponds a decrease in sensitivity both impact electric spark. O1s is mostly inversely energy directly proportional that sparks. For detonation rates, pure are proportional; CACs, however, this relationship proportional. These findings supported by analogous relations with crystal density, especially case 1s. In terms co-crystal identification among there auxiliary exist between on one hand Raman ring deformation vibration (wrt FTIR symmetric N-O stretching other. All relationships discussed. Hirshfeld CL20 shows more stable intermolecular fingerprint plots its β-isomer than ɛ-analog, which might reason stabilization nitramine co-crystals.
