The synthesis of atomically precise clusters is nowadays well established. The study of isolated clusters in the gas phase has also become an approved field of research. Although both approaches examine the same research objects, namely nanoclusters, little is known about to what extent results from gas phase studies can be transferred to colloidal systems and vice versa. In particular, it is not yet sufficiently understood how ligands influence the geometric and electronic structure of clusters from an experimental point of view. By comparing a ligand-stabilized tin nanocluster in solution with an isolated species in the gas phase and considering different geometric arrangements with the same number of tin atoms, the impacts of ligand stabilization, molecular symmetry, and solvatochromism on the optical behavior are thoroughly worked out for the first time.

原子精确的Sn14纳米团簇的光吸收：配体稳定，分子对称性和Solvatochromism的拮抗相互作用。

如今，原子精确团簇的合成已经很成熟。气相中孤立簇的研究也已成为公认的研究领域。尽管两种方法都研究了相同的研究对象，即纳米团簇，但人们对气相研究的结果可转移到胶体体系的程度知之甚少，反之亦然。特别地，从实验的观点来看，还没有充分理解配体如何影响簇的几何和电子结构。通过比较溶液中配体稳定的锡纳米团簇与气相中的分离物种，并考虑具有相同锡原子数的不同几何排列，对配体稳定化，分子对称性的影响，
