High-resolution absorption spectrum of the rotational-vibrational 2ν3 band of the S18O2 molecule has been registered for the first time. An analysis of the band by the method of combination differences allows rotational-vibrational structure of the (v = 2, A1) state to be determined. The inverse spectroscopic problem is solved based on the data obtained.
