Application of THz spectroscopy methods for detection of ecotoxicants for environmental monitoring purposes

The work is devoted to applications of terahertz spectroscopic technique and methods for ecological applications and monitoring. Preliminary quantum-chemical calculations of rotational spectra of some chlorine-containing substances studied were carried out. The measurements of the absorption lines of the rotational spectrum for a number of chlorine-containing substances (dichloromethane, chloroform) were carried out in the 2-mm range using spectrometers developed by the authors. The spectroscopic absorption lines of some chlorine-containing substances, revealed during the investigations, can be used for ecological monitoring.
