We have studied the classical and quantum dynamics of the Morse system driven by time-periodic external field. Floquet energies and Husimi probability distributions of quasibound states of the driven system are obtained using exterior complex scaling method and Floquet theory. As we increase the external field strength, the number of quasibound states is decreased and the Husimi distribution of the quasibound state shows the enhanced positive momentum distribution that appears to be supported by the classical homoclinic tangles that develop on the positive momentum side of the phase space.
