By the theoretical analysis of zero-points of the transition dipole of CO2, we obtain very accurate formulae describing a connection between three quantities: interatomic separation, electron kinetic energy in the continuum region, angle between electron direction and molecular axis. These formulae are very similar to the Bragg’s equations for the electron interference effect and allow us to obtain the interatomic separation form the high-order harmonic spectra. Therefore, an effective method for retrieval of interatomic separation of CO2 from high-order harmonic generation is proposed. This method can be applied for other molecules having two centers of emitting electrons.
