This localization must be closely related to the non-existence of the so-called S= 1/2 edge states in the S= 1 dimer phase (Ref. 9). If we weaken dimerization to enter the Haldane phase, the edge states show up and this type of excitations will dissociate into two S= 1/2 objects.

3>0, however, an excited state corresponding to one a tetrahedron in the RD background and that in the sea of 2 tetrahedra should be considered quite different from each other.
