This talk presents an analytical theory of strong field ionization in systems with multiple interacting electrons. Because the electrons can interact, they may rearrange during the tunneling process, providing an alternative pathway for orbitals other than the highest occupied molecular orbital (HOMO) to be vacated. This pathway is not subject to the full exponential energy suppression accompanying direct tunnel ionization from the more deeply bound orbitals. Interaction of electrons during the tunneling process can be modeled as an "attosecond correlation pulse," which depends on molecular structure and orientation as well as the parameters of the laser field.
