Title: First analysis of the rotationally-resolved ν 2 and 2ν 22 bands of sulfur dioxide, 33S 16O 2

A Fourier transform spectrum of sulfur dioxide 33S 16O 2 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 ν 2 and 2ν 22 vibrational bands of the 33S 16O 2 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: ν 02) = 515.659089(50) cm $-$1, ν 0 (2ν 2) = 1030.697723(20) cm $-$1.
