Abstract: In the present study, the high resolution infrared spectra of the 32S16O18O molecule were recorded for the first time with a Bruker IFS 120 HR Fourier transform interferometer and analyzed in the region of 1550 - 1950 cm−1 where the bands ν1+ν2 and ν2+ν3 are located. Around 1050 and 1570 transitions were assigned in the experimental spectra with the maximum values of quantum numbers max. max. / a J K equal to 64/16 and 58/19 to the bands ν1+ν2 and ν2+ν3, respectively. The subsequent weighted fit of experimentally assigned transitions was made with the Hamiltonian model, which considers the resonance interactions between the studied vibrational states. As the result, a set of 16 fitted parameters was obtained which reproduces the initial 1442 ro-vibrational energy values obtained from the assigned transitions with the drms = 3.7 × 10−4 cm−1.
