In this work, we present initial results of time-domain Fourier transform spectroscopy in the THz frequency range (from 1 to 20 THz) to detect and identify explosives and related compounds (ERCs). Comparison is made with conventional FT-IR spectroscopy. A comparison can also be make with the results of chemical modeling calculations (reported previously) to obtain spectroscopic information on ERCs and environmental background.
