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.

利用电子跃迁的高分辨斯塔克光谱研究了分子范德华络合物。氦纳米粒子内部这种复合体的形成是由长距离的伦敦弥散力决定的。实验和理论研究相结合，揭示了长程伦敦色散力对这种复合体构型的影响。除了分子络合物之外，到目前为止所获得的结果还显示了研究氦液滴中分子的微溶剂化的一个有趣的方面。因此，非极性有机分子与氦原子之间的色散相互作用占主导地位。这是一个由伦敦分散力量驾驭的极端例子。
