Magnetic Clusters

在实验物理化学，化学分部的这个项目中，Weltner教授（U. Florida）将使用电子自旋共振和傅立叶变换红外光谱来研究低温下稀有气体基质中捕获的金属，碳和半导体簇。该工作的新方面包括微晶金属颗粒的红外光谱和ESR光谱的磁场依赖性。韦尔特纳教授（佛罗里达大学）将在低温下捕获非常小的金属和半导体颗粒，并使用红外和射频辐射对它们进行研究。这是很重要的，因为它提供了基本的信息，如何组装的分子相互作用，以提供理想的性质的大块材料。

In this project in Experimental Physical Chemistry, Chemistry Division, Prof. Weltner (U. Florida) will use Electron Spin Resonance and Fourier Transform Infrared Spectroscopy to study clusters of metals, carbon, and semiconductors trapped at low temperatures in rare gas matrices. Novel aspects of the work include magnetic field dependence of IR spectra and ESR spectra of microcrystalline metal particles. %%% Prof. Weltner (U. Florida) will trap very small particles of metals and semiconductors at low temperatures, and study them using infrared and radio frequency irradiation. This is important because it provides fundamental information on how assemblies of molecules interact to give desirable properties of bulk materials.
