title = "Terahertz spectroscopy of energetic materials",
abstract = "Recently, terahertz spectroscopy has attracted increasing interest as a probe of organic molecular crystals such as pharmaceutical compounds and explosives. Terahertz time-domain spectroscopy (THz-TDS) focuses on low-frequency (10-120 cm-1) intermolecular modes that are characteristic of the crystal structure. The prospect of material-specific identification, combined with the ability of THz light to penetrate many common materials, has lead to an emphasis on the prospect of a THz-based, standoff explosives detection device. In this presentation, THz spectra of materials ranging from military-grade explosives to home-made explosive components will be discussed. In addition to the experimental results, THz spectral assignments will be presented based on solid-state density functional theory simulations. Finally, the effect of particle size on the observed spectra will also be considered.",
