The relativistic RPA approaches are applied to calculate the charge‐exchange spin flip resonances. Comparing the RPA calculations based on the relativistic Hartree and relativistic Hartree‐Fock theories, the different physical mechanisms in determining the Gamow‐Teller resonance are investigated. Then, the theoretical descriptions of spin‐dipole and spin‐quadrupole resonances are presented. In particular, the energy hierarchies of different components in these resonances are focused on.
