Abstract
X-ray photoelectron spectroscopy (XPS) and Fourier transform nuclear magnetic resonance (FT-NMR) were used to characterize 1,3,5-triamino-2,4,6-trinitrobenzene. The XPS results showed approximately equal signal intensities of N 1s electrons from NO2 and NH2; this agrees well with the theoretically calculated values. An increase in the NH2/NO2 ratio was observed after ultraviolet or X-ray irradiation. FT-NMR at proton frequency showed a characteristic Pake's doublet due to strong proton dipole-dipole interaction in solids. Surface moisture absorption was observed when the samples were exposed to a humid environment. The moisture molecules were found to be partially bonded to the surfaces or diffused into the crystal lattice after an extended exposure period.
