A number of experiments involving laser induced fluorescence and laser excitation will be carried out in the proposed research.  The main emphasis will be to elucidate the spectroscopic properties of the triatomic mercury molecule as well as mercury clusters containing four to six atoms.  Clusters of atoms provide the important data on why there are differences between the properties of the vapour and the liquid or solid forms of the material.  It is well known that the toxic properties of mercury depend on whether it is in the vapour phase or in the liquid phase, and it is hoped to establish structural information which can lead to advances in this knowledge as well as basic knowledge for comparison to theoretical results and hence to check the validity of the theoretical models.  The work should complement work carried out elsewhere on mercury clusters and cluster ions which contain many more atoms.

这项研究将进行多项涉及激光诱导荧光和激光激发的实验，重点将是阐明三原子汞分子以及含有四至六个原子的汞团簇的光谱特性。原子团簇提供了重要的数据，说明为什么物质的蒸气和液体或固体形式之间的性质存在差异。众所周知，汞的毒性取决于它是处于气相还是液相，希望能为汞团簇和团簇离子的研究提供结构信息，并为与理论结果的比较提供基础知识，从而检验理论模型的有效性，补充前人在汞团簇和团簇离子方面的工作含有更多的原子。
