A Fourier transform spectrum of sulfur dioxide 33S16O2 has been recorded in the 18.3 μm spectral region at a resolution of 0.002 cm$$-$$1 using a Bruker IFS 125HR spectrometer leading to the observation of the ν2 and 2ν22 vibrational bands of the 33S16O2 molecule. The corresponding upper state ro-vibrational levels were fit using Watson-type Hamiltonians. In this way it was possible to reproduce the upper state ro-vibrational levels to within the experimental uncertainty; i.e., ~ 0.20 × 10$$-$$3 cm$$-$$1. Finally, very accurate rotational and centrifugal distortion constants were derived from the fit together with the following band centers: ν02) = 515.659089(50) cm$$-$$1, ν0 (2ν2) = 1030.697723(20) cm$$-$$1.
