We investigate the ionization of N{sub 2} and CO{sub 2} using the strong-field approximation (SFA) in both the length gauge (LG) and the velocity gauge (VG). Comparisons have been made among the different versions of SFA, the molecular Ammosov-Delone-Krainov (ADK), and recent experiments. The study also shows that the VG SFA displays a larger laser parameter (intensity and wavelength) dependence than the LG SFA, which is not observed in experiments and first principal calculations. The LG SFA is preferable for description of the strong-field ionization of N{sub 2} and CO{sub 2}.
