| Research Abstract |
This project has aimed to establish the experimental reconstruction of wave functions pertinent to the degrees of motion characteristic to molecules, i.e., vibration and rotation, and to develop the control technology for creating molecular quantum states as designed. We have made the following achievements: (1) construction of an ion-imaging setup with new configuration and successful application to real-time trucking of propagation of unidirectionaly rotating wave packets, (2) proposal of a new coherent population transfer method based on non-resonant stimulated Raman excitation with frequency-chirped pulses and development of a novel nanosecond pulsed light source to realize the new method, and (3) detailed examination of intermolecular motion in clusters with benzene and hydrogen molecules by adopting high-resolution electronic spectroscopy.
