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.

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部门气相光电子能谱仪。这一设备将加强若干领域的研究，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）评价辅酶模型复合物中的铯-硫相互作用; d）卟啉和金属卟啉的电子结构。 X射线光电子能谱仪（XPS）用于化学分析。 它用一束单色X射线照射样品，测量产生的光电子的能量并将其与特定元素联系起来。 XPS通常在定义所研究的系统方面起着至关重要的作用。 这些研究人员将开展的工作代表了对材料化学和生物学前沿一系列问题的高度一致的攻击。
