چکیده انگلیسی
The geometries of nine CHNO nitro-contained explosive molecules were fully optimized employing the B3LYP method of density functional theory with the 6-31G* basis set. The bond dissociation energy (BDE) for removal of the NO2 group in nitroamine molecules with nitro alkyl, and benzoate with nitro alkyl were calculated at the same level. The calculational results of B3LYP/6-31G* and B3P86/6-311G* levels showed that the strength of C-NO2 is weaker than that of N-NO2 bond in nitroamine molecules with nitro alkyl. The weakest bond is the C-NO2 in these computed molecules. The relationship between the impact sensitivities and the weakest C-NO2 bond dissociation energy values was examined. The results indicate a nearly linear correlation between the impact sensitivity and the ratio of the BDE value to the molecular total energy.
