In this project supported by the Experimental Physical Chemistry Program of the Chemistry Division, Weltner will use electron spin resonance (ESR), electron-nuclear double-resonance (ENDOR), Raman and infrared spectroscopies to study the spectra of transient molecules, ions, and clusters trapped in low-temperature matrices consisting of rare-gas and hydrogen hosts. Transition metal, rare-earth metal, Group III, supercritical carbon dioxide, and other open-shell carbon-based molecules and their derivatives will be characterized for information about their bonding. In this study Professor Weltner will trap highly reactive species in solids at very low temperatures in order to determine their structures and measure their electrical and magnetic properties. The broad range of experimental techniques used in these investigations provides a unique and significant source of data on a broad range of molecules, ions, and clusters which is difficult to gather by other methods. Such data are important for refining theoretical calculational methods as well as for understanding such processes as heterogeneous catalysis and semiconductor manufacture.

在这个由化学学部实验物理化学项目支持的项目中，Weltner将使用电子自旋共振（ESR）、电子-核双共振（ENDOR）、拉曼和红外光谱来研究被困在由稀有气体和氢气组成的低温基质中的瞬态分子、离子和簇的光谱。过渡金属、稀土金属、III族、超临界二氧化碳和其他开壳碳基分子及其衍生物将被表征，以获得有关它们成键的信息。在这项研究中，韦尔特纳教授将在极低的温度下将高活性物质捕获在固体中，以确定它们的结构并测量它们的电和磁特性。在这些研究中使用的广泛的实验技术为广泛的分子、离子和簇提供了独特而重要的数据来源，这是其他方法难以收集的。这些数据对于改进理论计算方法以及理解诸如多相催化和半导体制造等过程是重要的。
