Molecular strong field ionization (SFI)is at the heart of several ultrafast imaging/spectroscopic techniques such aslaser induced electron diffraction and high harmonic spectroscopy. Whileproof-of-principle experiments are underway, it is still a long way before theycan evolve into a standard imaging techniques. The coupled motion of electronsand nuclei under the influence of a non-perturbative external laser field isnot fully understood yet and there is a strong demand for developing many bodymethods that can model these molecular SFI based processes.

I will present in this talk, the making of the hybrid coupled channels approach, one of the first multi-electron methods that has been realized in this context, by covering a range of technical aspects such as the construction of accurate channel functions, choice of gauge, linear dependency issues and so on. Using examples, I will demonstrate the role of multi-electron effects: Exchange, core electron polarization and inner orbital ionization in molecular SFI.
