The impact of the isoscalar proton-neutron (pn) residual interaction on magnetic dipole strength distributions is investigated for the examples 46,48Ti. Shell-model calculations with different interactions are performed, where either the full set of T = 0 two-body matrix elements (TBME) from the FPD6 effective interaction, a set of constant TBME, or no TBME at all are considered. The comparison with experimental data from high-resolution electron scattering reveals clear experimental signatures of the T = 0 pn interaction part.
