| Izvleček: | Title screen The infrared spectrum of the H2S molecule is recorded using a Bruker IFS 125HR Fourier transform spectrometer and studied in the range of 4500-5000 cm-1, in which the first hexad of bands of interacting states of the hydrogen sulfide molecule is located (in this particular case, weak band 4ν2ν2 is studied). Four hundred transitions with maximum quantum numbers of JmaxJmax = 17 and KmaxaKamax = 8 are assigned in the experimental spectrum. These transitions correspond to one hundred thirty two upper vibration-rotation energy levels. The obtained data are analyzed using Watson's model of the effective Hamiltonian. By solving the inverse spectroscopic problem, a set of twenty eight spectroscopic parameters was obtained, which reproduces the initial experimental data with a standard deviation of drmsdrms= 3.5 × 10-4 cm-1.
