We study pion absorption on ${}^3\mathrm{He}$ employing trinucleon wave functions calculated from modern realistic $\mathrm{NN}$ interactions (Paris, CD-Bonn). Even though the use of genuine trinucleon wave functions leads to a significant improvement over older calculations with regard to both cross section and polarization data, there are hints that polarization data with quasifree kinematics cannot be described by just two-nucleon absorption mechanisms.
