We investigate the eect on high-order harmonic generation of the distortion of molecular orbitals by the driving laser eld. Calculations for high-order harmonic generation including orbital distortion are performed for N2 (high polarizability). Our results allow us to suggest that field-distortion is the reason why the two-center interference minimum has never been observed experimentally in N2. We propose experimental parameters which should allow an observation of the two-center interference minimum. Calculations for CO2 (low polarizability) further validate the theory by revealing the survival of the minimum in the high-order harmonic spectra. This is in agreement with experiment.
