| Outline of Final Research Achievements |
We have developed "quantum-wave-packet imaging spectroscopy", where intense ultrashort laser pulses have been implemented to create rotational quantum wave packets of molecules, and spatiotemporal evolution of molecular orientation has been captured via time-resolved Coulomb-explosion imaging. By using an optical setup with > 10 ns delay time, we realize < 100 MHz frequency resolution. The present approach has been applied to observe pure rotational transitions of a number of weakly bound molecular clusters, such as rare-gas dimers, ethylene dimer and trimer, and dimers of nitrogen molecules, methane, and propylene.
