  Laser-induced-continuum-structure(LICS) allows for coherent control
techniques to be applied in a Raman type system with intermediate continuum
state. To this end the standard LICS problem treats two bound states coupled to
one or more continua states. In this paper we discuss the simplest non-trivial
multilevel generalization of LICS coupling two bound levels, each composed of
two degenerate states through a common continuum state. We reduce the
complexity of the effective system of bound states by switching to a rotated
basis in which different sub-systems of lower dimension evolve independently.
We derive a trapping condition and explore the dynamics of the sub-systems
under different initial conditions.
