Abstract:\begin{wrapfigure}{r}{0pt} \includegraphics[scale=0.25]{Fig_iso_RuO4.eps} \end{wrapfigure} ~ The study and analysis of heavy spherical-top molecules is often not straightforward. The presence of hot bands and of many isotopologues can lead to a high line congestion very difficult for assignment. In this work, using a low-order model we have derived very simple isotopic relations in order to determine initial parameters of the analysis. We also show that an identical approach can be used for $XY_4$ and $XY_6$ molecules and all these results are illustrated by the comparison of numerical computations and experiments for different molecules: CH$_4$, GeH$_4$, RuO$_4$ (as shown in the figure on the right) and SF$_6$. ~ Reference: M.
