The hot 2ν2 + ν3 – ν2 hybrid band of the S18O16O molecule is assigned in the range 1800–1900 cm–1 for the first time. The spectrum is analyzed based on the method of combination differences. 56 energy levels (Jmax = 15, Kamax=12) are determined based on the experimental data obtained. Rotational parameters of the (021) vibrational state are determined.
