I discuss first the effect of decoupling of extended wave functions and the coherence in the low-energy E1 strength in drip line nuclei 12Be and 13O, which are studied by large-scale shell model calculations including 3 configuration space. The calculated results are compared to recent experimental data of Coulomb excitations. The quenching of the core polarization charges in drip line nuclei is also discussed in relation to recent observations of quadrupole moments in B-isotopes.
