| contents | In this work, we investigate the nonlinear dynamics of molecules with an octahedral configuration, with particular focus on sulfur hexafluoride SF6. Under the assumption of isotypic nonresonance, we apply the method of equivariant gradient degree to prove the existence of branches of periodic solutions emerging from the critical orbit of equilibrium, corresponding to at least 16 distinct types of symmetries with maximal orbit kinds. Numerical animations are presented to illustrate the detected vibrational modes. |
