The control of dissociation pathways of H2+ through individual manipulations of nuclear vibration and electronic transfers is theoretically studied by using the two-color mid- and near-infrared laser fields. We show that the time-delayed weak near-infrared pulse can steer the electron localization by directly manipulating the electronic transfers in the one-photon coupling region with minor influence on the nuclear motion. Our further results demonstrate that the nuclear and electronic dynamics can be efficiently and individually controlled by changing the relative phase between the two laser pulses. The best balance between the nuclear and the electronic motions and, thus, the further enhancement of electron localization compared to that of a single midinfrared field, are ultimately achieved [ABSTRACT FROM AUTHOR]
