Upgrade of a Departmental Gas-Phase Photoelectron Spectrometer

在化学研究仪器和设施(CRIF)计划的支持下，亚利桑那大学化学系将升级系内的气相光电子能谱仪。该设备将加强一些领域的研究，包括：a)金属-金属相互作用的研究；b)含杂原子的有机化合物中的电子转移；c)钼酶模型络合物中钼-硫相互作用的评估；以及d)卟啉和金属卟啉的电子结构。X射线光电子能谱(XPS)用于化学分析。它用一束单色X射线照射样品，产生的光电子的能量被测量并与特定的元素相关。XPS通常在定义研究中的系统方面发挥关键作用。这些调查人员将开展的工作代表着对材料、化学和生物前沿的一系列问题的高度一致的攻击。

With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of Arizona will upgrade a departmental gas-phase photoelectron spectrometer. This equipment will enhance research in a number of areas including the following: a) studies of metal-metal interactions; b) electron transfer in organic compounds containing heteroatoms; c) evaluation of molybdenum-sulfur interactions in molybdoenzyme model complexes; and d) electronic structure of porphyrins and metalloporphyrins. The X-ray photoelectron spectrometer (XPS) is used for chemical analysis. It irradiates a sample with a beam of monochromatic X-rays and the energies of the resulting photoelectrons are measured and related to specific elements. XPS often plays a crucial role in defining the system under study. The work to be carried out by these investigators represents a highly coherent attack on a range of issues at the forefront of materials chemistry and biology.
