Time resolved terahertz spectroscopy of explosive materials

We studied terahertz spectra of hexanitrohexaazaisowurtzitane ('varepsilon'-HNIW and 'gamma'-HNIW), a kind of explosive materials, using terahertz time-domain spectroscopy (THz-TDS) in the 0.2-2.5 THz region. The experimental results show that explosive samples with different conformations have diff
