Abstract

One of the features of the H₂S molecule is quite weak intensity of the fundamental bands. Another feature is anomalous distribution of intensity over branches and its dependence on the rotational quantum number K. Correctly calculated parameters of the dipole moment function for the H₂S molecule allowed us to estimate the first and second rotational corrections in the transition moment operator for the fundamental bands. The calculated corrections appeared from the vibration-rotation coupling well reproduce the unusual intensity pattern of the P, Q and R branches in the H₂S molecule.
