Abstract. Nowadays studying the kinetics of chemical reactions is very important for solving problems of detonation physics, growth of hi-tech structures, etc. With using the high precise THz spectroscopy the kinetics of thermal decomposing the high energy materials (by the example of ammonium nitrate) and detecting the decomposition products both at room temperature and at heating in linear and isothermic modes as well as staging of decomposition processes have been studied. The absorption lines of ammonium, nitrous oxide and nitric acid have been registered. The yield time and yield temperature of the decomposition products as well as the number of reaction have been determined. The prospective of using the high precise THz spectroscopy for studying the kinetics of thermal decomposing the high energy substances, determining the process staging and developing the reliable kinetic models has been shown.

Key words: terahertz frequency range, high precise non-stationary spectroscopy, high energy substances, kinetics of thermal decomposition, ammonium nitrate.
