The research project is about establishing a methodology to carry out experiments on isomer-selected metal clusters in molecular beams. To do this, the first step is to enrich a structural isomer and the second step is to examine the physico-chemical properties of enriched isomer. The enrichment takes advantage of the fact that the structural isomers have different electrical or magnetic susceptibilities, i.e. they differ in the Stark or Zeeman effect and therefore have different polarization or magnetization. With the help of an electrical or magnetic deflector, different structural isomers can be separated from one another, so that at least a spatial enrichment of a structural isomer is achieved. To determine the chemical composition of the molecular beam the Stark or Zeeman effect can be again used. In addition, spectroscopic investigations are intended, using photodissociation and photoionization spectroscopy to address the optoelectronic behavior and the redox properties of the enriched structural isomers. The establishment of such experiments for isomer-selected separation and investigation are groundbreaking for a deeper understanding of metal clusters and their future applications in catalysis and sensing.

该研究项目是关于建立一种方法，在分子束中对异构体选择的金属团簇进行实验。为此，第一步是富集结构异构体，第二步是检查富集异构体的物理化学性质。富集利用了结构异构体具有不同的电或磁磁化率的事实，即它们在斯塔克或塞曼效应方面不同，因此具有不同的极化或磁化。借助于电偏转器或磁偏转器，不同的结构异构体可以彼此分离，从而实现结构异构体的至少空间富集。为了确定分子束的化学成分，可以再次使用斯塔克或塞曼效应。此外，光谱调查的目的，使用光解离和光电离光谱，以解决光电行为和氧化还原特性的丰富的结构异构体。这种异构体选择性分离和研究实验的建立对于更深入地理解金属簇及其在催化和传感方面的未来应用具有开创性意义。
