Results show that the laser-induced electron transfer process between the vibrational state and the ground electronic state is responsible for the resonant peak on the harmonic spectrum, and that the two ionization pathways are behind the two identified cutoff energies. In addition, by optimizing the asymmetric harmonic emission, the generations of the ultrashort attosecond pulses are also discussed.
