1,3,5-Triamino-2,4,6-trinitrobenzene (TATB) is a typical insensitive high explosive (IHE) that possesses excellent heat, impact, and shock stability. However, it is sensitive to light irradiation, which can produce a long-lived free radical. In this study, (time-dependent) density functional theory is employed to study the features of the ground state (S0),(More)
A combination of the advanced chemometrics method with quantum mechanics calculation was for the first time applied to explore a facile yet efficient analysis strategy to thoroughly resolve femtosecond transient absorption spectroscopy of ortho-nitroaniline (ONA), served as a model compound of important nitroaromatics and explosives. The result revealed(More)
IR spectra of TATB at different temperature were investigated for vibrational assignments. The results showed that the hydrogen bonding interaction of TATB was significantly weakened with increasing the temperature. Based on the frequency shifts of the hydrogen bonding interaction to several vibrational modes, 12 absorbance bands in the region 600-1700(More)
