  We propose a novel scheme for probing vibronic coherence in charge migration
in molecules utilizing strong field sequential double ionization. To
demonstrate the feasibility of this approach, we perform full simulations of a
pump-probe scheme employing few-cycle intense infrared pulses for N$_2$ and
O$_2$. We predict that the vibronic coherence between the pumped states will be
directly imprinted in experimental observables such as kinetic energy release
spectra and branching ratios of the dissociative dications. Our simulations are
based on the recently developed DM-SDI model, which is capable of efficiently
accounting for molecular orientations and enabling direct comparison with
experimental results. Our findings strongly encourage the use of this probing
scheme in future charge migration experiments.
