Lie algebraic approach to multiphoton rovibrational transition of diatomic molecule in intense laser fields Original Research Article

The multiphoton rovibrational excitation of diatomic molecule in intense laser fields is studied by using simulated potential and Lie algebraic approach. The rovibrational transition probability as a function of external field frequency and time, respectively, for the molecules HF, NO and LiH is calculated. The influences of the rotation on the multiphoton processes are investigated.
