We investigate the effect on high-order-harmonic generation of the distortion of molecular orbitals by the driving laser field. Calculations for high-order-harmonic generation including orbital distortion are performed for N2. 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.
