Abstract. The possibility of developing the high resolution terahertz (THz) spectrometer which is intended for solving of wide range of problems was considered. Gas spectrometer with using of the synthesizer based on Gunn generator and frequency multiplier with semiconductor superlattice (SL) as a radiation source and NbN hot electron bolometer (HEB) mixer in the mode of radiation detector as a receiver system was proposed. Experimental results of spectrometer operation were presented: the H2O (1.92 THz, 17th harmonic) and HDO (1.49 THz, 13th harmonic) absorption lines were registered. The results performed were analyzed and further possibilities of improving the spectrometer characteristics as well as spectroscopy investigations were considered.

Key words: terahertz frequency range, high precise spectrometer, semiconductor superlattice, radiation source, mixer.
