Configurations of van der Waals complexes controlled via London dispersion forces as revealed by means of Stark spectroscopy in He-nanodroplets

利用高分辨率斯塔克光谱对电子跃迁分子范德华配合物进行了研究。氦纳米小波内这种复合物的形成是由长程伦敦色散力决定的。结合实验和理论研究，揭示了长程伦敦色散力对这种复合物结构的影响。除了分子复合物之外，迄今为止获得的结果显示了研究氦液滴分子微溶剂化的项目的一个有趣方面。因此，非极性有机分子与氦原子之间的色散相互作用起主导作用。这是伦敦色散力操纵的一个极端例子。

By means of high resolution Stark spectroscopy on electronic transitions molecular van der Waals complexes are studies which. The formation of such complexes inside helium nanodorplets is determined by long rage London dispersion forces. Combined experimental and theoretical investigations head to reveal the influence of long rage London dispersion forces on the configuration of such complexes. In addition to molecular complexes the results obtained so far show an interesting aspect of the project to study microsolvation of molecules in helium droplets. Thereby, the dispersion interaction between non-polar organic molecules and helium atoms plays a dominant role. This is an extreme example for steering by London dispersion forces.
