| Abstract: | We have constructed the algebraic vibration Hamiltonian and time evolution operator for the linear triatomic molecule in the intense laser fields by using the quadratic anharmonic model and Magnus approximation.The relations between the multiphoton transition probability of the DCN molecule and the frequency and intensity of the external field are discussed. |
