In the final stage of fission, the fissioning nucleus can be described by two nuclei in close proximity. The Hamiltonian of the system at this stage can be expressed as the sum of the Hamiltonians of two independent fragments and coupling terms between them. The coupling terms are, roughly speaking, divided into two types: (i) particle transfer type and (ii) density-density type. By making use of extremely schematic models, the relation between the collective modes and the coupling terms is investigated. As for the particle transfer correlation it is shown that the monopole-monopole type interaction leads us to the asymmetric mass division in low energy fission. Furthermore it is discussed that angular vibrational mode, which is associated with the angular orientations of fragments, is derived from the quadrupole-quadrupole interaction.
