### Abstract

Transitions belonging to the three “hot” bands of the S^{18}O_{2} molecule, ν_{1}+ν_{2}+ν_{3}−ν_{2} (621 transitions with the values of quantum numbers J^{max}=49 and K_{a} ^{max}=14), 2ν_{1}+ν_{2}−ν_{2} (332 transitions with J^{max}=42 and K_{a} ^{max}=12) and 2ν_{2}+ν_{3}−ν_{2} (15 transitions with J^{max}=14 and K_{a}=8 and 9), were assigned in the spectral 2100–2700 cm^{−1} region. This enabled for the first time to get high accurate values of 388, 185 and 13 ro-vibrational energies for the highly excited vibrational states (111), (210) and (021), respectively. A weighted fit analysis using the obtained ro-vibrational energies allowed us to generate a set of 20 fitted parameters which reproduce the initial 586 energy values (about 970 assigned experimental transitions) with the d_{rms} deviations of 1.9×10^{−4}cm^{−1}, 2.8×10^{−4} cm^{−1} and 2.5×10^{−4} cm^{−1} for the states (111), (210) and (021).
