Abstract

The dynamics of vibrational wave packets excited in Na2 dimers in the triplet ground and excited states is investigated by means of helium nanodroplet isolation (HENDI) combined with femtosecond pump-probe spectroscopy. Different pathways in the employed resonant multiphoton ionization scheme are identified. Within the precision of the method, the wave packet dynamics appears to be unperturbed by the helium droplet environment.

摘要

利用氦纳米液滴隔离（HENDI）结合飞秒泵浦-探测光谱技术，研究了处于三重态基态和激发态的Na2二聚体中激发的振动波包的动力学。确定了所采用的共振多光子电离方案中的不同路径。在该方法的精度范围内，波包动力学似乎不受氦液滴环境的干扰。
