| Stability of motions for different potential functions describing vibrational motions of rotating molecule has been discussed. It was shown that an equilibrium position for nonrotating r0 and rotating rJ molecules for almost all the examined potentials is a node, but for the molecule described by the soft body model a critical value of rotation quantum number Jc occurs above which r0 is a saddle point, and the stable motion may occur only around rJ. |
