N2 - High-order harmonic generation (HHG) spectrum of an atom interacting with a bichromatic laser field was investigated a dynamical symmetry analysis (DSA). The HHG spectrum was calculated using a single Floquet state with in the framework of the conventional Hermitian quantum mechanics (QM). It was observed that the HHG spectrum was invariant under the transformation of phase, Ø → Ø + π. The results show that as the photoinduced ionization rate of decay is increased, the strength of the effect of the Ø → - Ø transformation on the HHG spectrum is increased.
