The multipole response of 3HeN drops doped with very attractive impurities, such as a Xe atom or an SF6 molecule, has been investigated in the framework of the Finite Range Density Functional Theory and the Random Phase Approximation. We show that volume (L = 0) and surface (L = 1, 2) modes become more fragmented, as compared with the results obtained for pure 3HeN drops. In addition, the dipole mean energy goes smoothly to zero when N increases, indicating that for large N values these impurities are delocalized in the bulk of the drop.
