bright yellow crystals
The color-changing of TATB appears on it's surface; it changes quickly under illumination.
After been illuminated (under natural light), free radicals appeared on the molecular structure of yellow TATB. The -NO2 group is excited, and activation energy decrease, which lead to reduction of fusing point, decomposition point and the explosion point.
We also observed from experiments that the color-changing of TATB occurs only after illumination. And it's color keep the same after 48h at 120°C basicly. After 2h at 200°C, it's color changes from yellow to light brown. The color of green TATB becomes deeper, which indicates that the high temperature will cause color change of TATB.
TATB exhibits both monoclinic and triclinic crystal structures.
Triclinic and monoclinic crystalline forms.
Optical Effects:
TATB is yellow and turns to shades of green when exposed to radiation from visible, ultraviolet (UV), electromagnetic, gamma, or 60Co sources.
The green color of TATB is caused by formation of an electronically excited state rather than by a new chemical species. The color varies from yellow-green to deep green to nearly black or brown-green. TATB turns dark yellow-brown on exposure to elevated temperatures. (Cady, 1961, Los Alamos National Laboratory)
