Sumario:Title screen
High resolution spectra of the H232S hydrogen sulfide are re-analyzed in the region of its first decade. Thanks to the improvement of the experimental conditions (in particular, an increase in both the instrumental resolution and the effective absorption path length by 1.5 times), on the one hand, and of the use of a more correct Hamiltonian model (which additionally takes into account the interactions of the bands under study with the ν1+4ν2 and 4ν2+ν3 bands), on the other hand, the information obtained as a result of the analysis of experimental data has been significantly expanded and improved compared to the previous status. In particular, (1) the total number of assigned lines has been increased by approximately 15 percent, (2) the maximum values of quantum numbers Jmax and Kamax for the assigned lines have been increased for the studied bands in average by 20–25 percent, (3) the number of obtained ”experimental“ energy levels of the upper vibrational states (especially for the (121) and (022) vibrational states) has been significantly increased, (4) despite the increase in the number of initial vibrational–rotational energies and quantum numbers Jmax and Kamax, the value of the standard deviation drms has improved 2.7 times for the obtained upper vibrational–rotational energies
