The possible constraints on the poorly determined symmetry part of the effective nuclear Hamiltonians or effective energy functionals, i.e., the so-called symmetry energy $S(\ensuremath{\rho})$, are very much under debate. In the present work, we show that the value of the symmetry energy associated with Skyrme functionals, at densities \ensuremath{\rho} around 0.1 fm${}^{\ensuremath{-}3}$, is strongly correlated with the value of the centroid of the Giant Dipole Resonance (GDR) in spherical…
