| Research Abstract |
Open-loop wave-packet engineering was demonstrated by full capture of the phase-controlled vibrational motions by means of our newly developed wave-packet spectrometer. Optimal parameters of tailored femtosecond pulses from a pulse shaper were obtained for selective excitation of either twisting or bending motion in two different cyanine dye molecules. Mode-selective wave-packet generation by chirped pulse sequences was found to be commonly effective for DTTCI, DNTTCI and SMP-39. These results suggest a promising step toward triggering chemical reactions to a desired target by guiding the wave-packet motions associated with conformational changes in the substances.
