Hydrogen sulfide spectra were recorded between 2150 and 2950/cm using a Fourier-transform spectrophotometer with resolution of 0.01/cm. An analysis of the spectra, combined with recent data on the ground state of H2(S-32), H2(S-33), and H2(S-34) led to an improved and extended set of rotational energy levels of the (020), (100), and (001) vibrational states of these isotopes. The rovibrational levels were subjected to a least squares fit using a Hamiltonian which accounts for the effects of the Coriolis resonance, and precise rotational and coupling parameters were determined. Measurements were made of 529 individual line intensities, making it possible to determine the expansion of the transformed transition moment operators of three bands, as well as the first derivatives of the dipole moment. Finally, a complete list of line positions and intensities of natural hydrogen sulfide is computed, and is expected to be of importance in the analysis of the infrared spectra of giant planets and in pollution studies.
