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.
