High-precision ion yields are taken with 30-fs ultrashort laser pulses in various species of doubly ionized diatomic molecules, N2 and O2, including metastable, charge symmetric, and asymmetric dissociating channels. The experimental results indicate that the detailed electronic structure is a critical factor influencing strong field nonsequential ionization. The study of ellipticity effects of nonseqential ionization is also extended, for the first time to our knowledge, to the molecular system.
