Анализ спектра высокого разрешения первой гексады молекулы H2 32S: полоса 4ν2

Abstract

The high-resolution infrared spectra of the H2 32S molecule were recorded with a Bruker IFS 125 HR Fourier transform interferometer in the region of the first hexad. In the present study, high resolution analysis was carried out for the 4ν2 band. Around 400 transitions were assigned in the experimental spectra with the maximum values of quantum numbers Jmax. /Kmax. A=17/8 and 132 upper energy levels were obtained. The weighted fit of experimentally obtained energy levels was made with the Hamiltonian model, which takes into account the resonance interactions between the studied vibrational states. As the result, a set of 28 fitted parameters was obtained which reproduces the original experimental data with the drm=3.5×10−4 cm −1.
