TERAHERTZ HIGH RESOLUTION GAS SPECTROSCOPY FOR THE ANALYSIS OF THE COMPOSITION OF PRODUCTS OF THERMAL DECOMPOSITION OF CEREALS GRAIN (OAT, BARLEY)
Abstract
We considered the fundamental principles of terahertz high resolution spectroscopy, based on the effect of free damping polarization, and the spectrometer in which this effect is realized in the regime of phase switching of radiation influencing gas. This approach is characterized by high selectivity and sensitivity, quickness of analysis, and safety. We analyzed the possibility of the use of terahertz high resolution spectroscopy in such agricultural applications as the component analysis of grain at its thermal decomposition. Measurements of the subterahertz spectra of samples of oats and barley at their thermal decomposition were carried out, and the absorption lines of various organic substances were identified.
