Experimental studies of the rotational spectrum of a methyl mercaptan molecule with sub-Doppler resolution have been performed. New advanced electrodynamic communication devices of spectrometer apparatus with a new absorber cell with a larger diameter have been developed and manufactured, taking into account the results of testing of the first version of such devices, and ensuring acceptable coordination of resistances in the entire operating range of the IRA NASU spectrometer. The technique of determining the absorption of electromagnetic waves in the atmosphere is introduced and a comparative analysis of its features in the two-band and single-band spectral observation modes is performed. A prototype of a single-band transceiver at 115 GHz has been developed to measure the absorption of electromagnetic waves in the Earth's troposphere. A database of the optical thickness of the atmosphere and the average temperature of the Earth's atmosphere for the winter-summer 2018 has been created.   Product Description popup.authors Iliushyn Vadym V.
