Abstract
The techniques of symmetry-adapted tensorial formalism and of vibrational extrapolation developed since many years by the Dijon group have proved their efficiency for the spectroscopy of spherical-top molecules $(CH_{4}, SF_{6},\cdots)$. We have extended these methods to the case of quasi-spherical tops such as $SO_{2}F_{2}^{a}$. This model has been used recently to perform the analysis of the ground state of this $molecule^{b}$. We present here a preliminary study concerning the analysis of the $\nu_{3}/\nu_{7}/\nu_{9}$ bending triad in the $550 cm^{-1}$ region. These results are compared to those obtained with the usual asymmetric-top $approach^{c}$. A set of programs for spectrum calculations and fits named $C_{2\nu}$ TDS has been used and is freely available at the URL: http://www.u-bourgogne.fr/LPUB/c2vTDS.html
