Abstract

Spectral investigations have been carried out regarding emission lines of different cosmic molecules within the wide frequency band from 1.5 GHz to 115 GHz. For this purpose high stable heterodynes have been introduced in order to register the spectra of different molecular transitions (transitions of rotational levels F1(3/2) - frequencies 1.6-1.8 GHz and F2(1/2) - frequencies 4.6-4.8 GHz), H₂O (transition 6₁₆-5₂₃ - frequency 22.235 GHz) and almost all known molecules, which are emitting within the 85-115 GHz band. In order to analyze the radiation spectra, special purpose equipment (wave analyzer) has been designed.
