Abstract. Nowadays the terahertz spectroscopy is considered to be one of the most
effective methods for identification of high energy substances and products of their
thermal decomposition in real-time mode. Analytical spectroscopy considers the vapor
of high energy substances and products of their decomposition as a multicomponent gas mixture, at that most of the components have intensive
absorption lines in the THz frequency range and can be unambiguously
identified. The results of studying the THz absorption spectra for gaseous
phase of high energy substances and products of their natural and thermal decomposition
have been presented. The decomposition products, being potential markers for
detecting the high energy substances in atmosphere in real-time mode, have been
revealed. A number of non-identified absorption lines which may be referred to
the high energy substances under study has been registered. The prospective of
using the high precise THz spectroscopy for qualitative and quantitative
detecting of high energy substances and products of their decomposition including
trace concentrations has been shown.
Key words: terahertz frequency range, high precise
non-stationary spectroscopy, high energy substances, products of natural and
thermal decomposition, detection.
