The enhanced ionization(EI) behavior of multiatomic molecular ions is studied in intense laser fields by the numerical solution of time-dependent Schrodinger eq uation with the symmetrical splitting of the short-time exponential propagator a nd fast fourier transformation(FFT).The influence of the intensity and the frequ ency of the laser on EI is given.With the laser frequency increasing,the criticl a value of bond length for EI decreases and the ionization probability decreases too.The ionization probability increases with increasing laser intensity.The EI disappeares when the intensity reaches a certain value.
