%X Trapping vibrational energy into one single bond is a key problem of bond-selective chemistry. We explored this possibility by means of restricting local mode wavepacket dephasing with multi-color laser field. The vibrational excitation and evolution of molecules in weak and strong multi-color laser fields are discussed by field-quantization method and semi-classical method. The results demonstrate that population can not be trapped in a local mode wave-packet using multi-color weak field, while it is possible to trap vibrational population between the ground state and local mode vibration by making use of power-broadening induced by strong laser field and the interference between two wave-packets excited by two strong laser of different frequencies.
