Effects of Skyrme tensor interactions on the spin-orbit splittings are studied by using Hartree-Fock-Bogoliubov model. The charge-exchange spin-dipole (SD) excitations of ~(208)Pb are also studied by using a fully self-consistent Skyrme Hartree-Fock plus Random Phase Approximation (HF+RPA) formalism including the tensor interaction. It is found that the tensor correlations have a unique, multipole-dependent effect on the SD excitations, that is, they produce softening of 1~? states, but hardening of 0~? and 2~? states. This paves the way to a clear assessment of the strength of the tensor terms.
