Abstract
The high resolution infrared spectra of the 34S16O2 molecule were recorded in the region of location of the 2ν1 and ν1+ν3 bands. The hot band ν1+ν2+ν3-ν2, which is located in the same spectral region, and the very weak band ν1+ν2+ν3 were also recorded and theoretically analyzed. Considerably more transitions, compared to the preceding studies, were assigned to the ν1+ν3 and ν1+ν2+ν3-ν2 bands. For the 2ν1 band more than 3280 transitions were assigned in the recorded spectra (only 16 transitions belonging to the 2ν1 band have been mentioned in the earlier literature). Ro-vibrational energies of the states (200), (101) and (111) were determined on the basis of the assigned transitions and then were used in the weighted fit procedure with the Hamiltonian model which takes into account the presence of resonance interactions. The obtained sets of parameters reproduce the initial experimental data with the accuracies close to experimental uncertainties.
