Abstract:\begin{wrapfigure}{r}{0pt} \includegraphics[scale=0.24]{GeH4_exp_sim.eps} \end{wrapfigure} Germane (GeH$_4$) is present in the atmospheres of the giant planets Jupiter and Saturn. Our recent analysis presented the complete modeling of line positions and intensities in the $\nu_1/\nu_3$ stretching dyad region near 2100~cm$^{-1}$\footnote{V. Boudon {\em et al.\/}, {\em J. Quant. Spectrosc. Radiat. Transfer} {\bf 205}, 174--183 (2018)}, of great interest for planetary applications. Nevertheless, this region contains a lot of hot bands. This situation leads to a very dense spectrum making deeper analyses difficult. In this study we present the first analysis and modeling of line positions in the $\nu_2/\nu_4$ bending dyad region for the five isotopologues. This analysis was conducted thanks to the formalism and programs developed in Dijon and allows to determine energy levels that are well suited for the hot band analyses, and therefore is a great improvement in the development of an accurate modeling needed for radiative transfer calculation for giant planets. These data will be integrated in our spectroscopic database (GeCaSDa\footnote{{http://vamdc.icb.cnrs.fr/PHP/gecasda.php}}) of calculated positions and intensities as soon as absolute intensities will be extracted from the spectra.
