The possibility of obtaining spectra of the complex refractive index of mononucleotide films deposited on a polished silicon substrate in the terahertz (THz) range has been shown for the first time. The transmission of biopolymer samples with a THz spectrometer was measured. The natural absorption frequencies and refractive index spectrum of adenosine in the THz range were defined.
