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

Abstract

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 2ν2- ν2 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 x 10-3 cm-1. Very accurate rotational and centrifugal distortion constants were derived from the fit together with the following band centers: ν0 (ν2) =515.659089(50) cm-1, ν0 (2ν2) = 1030.697723(20) cm-1.
