Rotational wave-packet imaging of molecules

摘要: We propose and illustrate numerically the possibility of imaging rotational wave packets in angular space time by using different pump-probe spectroscopic techniques. A general theoretical framework to perform such mapping is derived three specific spectroscopies, namely, birefringence, high harmonic generation, angle-resolved photoelectron spectroscopy, are explored. All approaches shown provide direct coherences molecules but they not equivalent; comparison their results yields interesting insights into relative merits. Finally, we role played symmetry molecular orbitals determining quality images generated signals. The potential as a route both intramolecular coupling mechanisms interaction with environments discussed.
