摘要：

We investigated the quantum-state distribution in nonadiabatic rotational excitation induced by a nonresonant intense laser field. NO molecules, initially prepared in the lowest J=0.5 state, were rotationally excited to states with up to J=8.5 at a laser intensity of 2.5x10(13) W/cm(2). The characteristics in the observed state distribution were quantitatively reproduced by a quantum dynamical calculation, and excitation pathways typical to molecules in a doubly degenerate state were identified.
