The application of microwave spectroscopy for on line analysis of the air irradiated by human

We report about the results of application of the microwave non-stationary spectrometer based on the effect of coherent spontaneous radiation for analysis of the air irradiated by human. Microwave spectrometer has a high sensitivity and resolution capacity both in millimeter and in sub-millimeter wavelength ranges. There are variety of absorption lines of human-produced molecules in these ranges. The results of exploration to detect ammonia, acetone, a number of complexes are reported. We also study the dynamics of above-mentioned molecules as well as that of ethanol and methanol at the processes of methabolism.
