Abstract:

The absorption spectrum of H2S molecule in the region from 5050 to 5257 cm–1 has been recorded with an UFS–02 Fourier spectrometer with the resolution of 0.0098 cm–1. Theoretical analysis of the recorded spectrum allowed us to identify 261 lines of 2ν1 and ν1 + ν3 bands. Also 175 rovibrational energy levels (up to J≤14 and Ka≤8) have been revealed, and rotational, centrifugal, and resonance constants of vibrational states (200) and (101) have been determined.
