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.

本项目的目标是建立与分子运动特征有关的波函数的实验重建，即振动和旋转，并开发按设计创建分子量子态的控制技术。我们取得了以下成就：(1)建立了具有新结构的离子成像装置，并成功地应用于单向旋转波包的实时传输；(2)提出了一种基于频率啁啾脉冲非共振受激拉曼激发的新的相干布居转移方法，并研制了实现该方法的新型纳秒脉冲光源；(3)利用高分辨率电子光谱详细研究了含苯和氢分子团簇中的分子间运动。
