Abstract

This work is a continuation of our theoretical analyses of the H₂S Fourier-transform spectrum, recorded in Kitt Peak National Observatory, in 2000 - 11,000 cm^-1 spectral region. This time we deal with 4,500 - 5,600 cm^-1 spectral region where the first hexad of vibrational bands (nu) ₁ plus (nu) ₃, 2(nu) ₂ plus (nu) ₃, (nu) ₁ plus 2(nu) ₂, 4(nu) ₂, 2(nu) ₁, 2(nu) ₃ are placed. In comparison with the previous work significantly more precise vibrational-rotational energy levels of the analyzed vibrational states have been obtained from the spectrum assignment, which was performed with the use of special computer program. The parallel refinement of the rotational and dipole moments parameters allowed us to make reliable predictional calculations and assign not only strong lines, included in combination differences, but a weak single lines also. Finally 1052 precise vibrational- rotational energy levels for all six members of the hexad have been derived in comparison with 542 from our previous work.
