We present previously unreported soliton bound states in the nonlinear Schrödinger equation, whose peculiarity lies in the vastly separated center frequencies of the constituent light pulses that are bound by Kerr-forces. This kind of soliton compound exhibits peculiar analogies to quantum mechanical binding energy, vibration, dissociation and dipolelike radiation. The key point relies on a formal analogy of trapping in potential wells in quantum mechanics, which can be realized by the interaction between two incoherent ultrashort solitons. The properties of the molecule states are investigated in detail and different ways for their creation are demonstrated.
