| Research Abstract |
The purposes of our research are development of a new vibrational spectroscopy using a nonresonant intense femtosecond pulse (pump pulse) and determining intermolecular potential energy surfaces (PES) of molecular clusters. In order to do this, dependence of vibrational population on delay time among a pair of double pump pulses is measured. We demonstrate that vibrational energy levels are determined by frequencies of the measured beat signals. Benzene dimer, trimer, and NO-Ar cluster are chosen as sample gases. For benzene clusters, new vibrational bands are found by this method. For NO-Ar cluster, observed vibrational bands have agreement with calculated ones. However, bands over 20cm-1 are not agreement among experiment and calculation. The fact shows that the PES has to be modified. In summary, we succeeded in developing the new vibrational spectroscopy and observing the new vibrational bands.
