标题： Microsolvation of phthalocyanine molecules in superfluid helium nanodroplets as revealed by the optical line shape at the electronic origin

摘要： 我们研究了掺入超流氦液滴中的酞菁（Pc）的溶剂位移，并通过光学光谱学在电子起源处进行探测。 我们目前的工作补充了现有的研究，并提供了部分与之前结论相矛盾的结果。 特别是，溶剂位移并不随着液滴半径的增大而持续增加直到体相极限，而是出现了转折。 此外，分辨出一个亚结构，其特征取决于液滴的大小。 这种行为很难与自由旋转的Pc-氦复合物的行为相协调。 显示英文摘要

摘要： We investigate the solvent shift of phthalocyanine (Pc) doped into superfluid helium droplets and probed by optical spectroscopy at the electronic origin. Our present work complements extant studies and provides results that in part contradict previous conclusions. In particular, the solvent shift does not increase monotonously with droplet radius all the way up to the bulk limit, but exhibits a turnaround instead. Moreover, a substructure is resolved, whose characteristics depend on the droplet size. This behavior can hardly be reconciled with that of a freely rotating Pc-helium complex.
