9503885 Meyer This U.S.-Brazil Cooperative Science Program award supports travel expenses for graduate students from the laboratory of Dr. Thomas Meyer, Univ. of North Carolina, Chapel Hill to the laboratory of Dr. N. Katz, Universidad Nacional de Tucuman, Tucuman, Argentina. Three visits of two month duration are supported. The Argentine side, in turn, will support three two month long visits by scientists from Dr. Katz' lab to the Univ. of North Carolina. Some expendable research supplies and publication costs are also supported under this award. The area of investigation is an important one, both as it relates to the basic understanding of photochemistry/physics and to more practical areas, such as solar energy conversion. The work will involve investigations in intramolecular electron transfer in a series of mixed- valence dimers containing Re(I, II) and Mo(I,0). These complexes will be designed such that the redox potential of photoinduced Re to Mo electron transfer can be varied by ligand modifications. In all cases the driving force will be greater than the reorganizational energy, so that the process occurs in the Marcus "inverted region". These studies will complement and extend Meyer's research on metal- ligand charge transfer in the inverted region , which has centered on monometallic complexes. Operationally, the strengths of the North Carolina and the Argentine groups will be efficiently utilized. While the design of the compounds is a joint responsibility, preparative work will be carried out in Tucuman, where the laboratory and personnel have much synthetic expertise. The complexes will then be transported to Nopth Carolina, where the photochemical experiments will be carried out, using Meyer's highly specialized laser facilities. In order to produce a coherent research team that effectively combines the individual talents of the two research groups, the research plan contains a detailed schedule for the interchange of workers b etween the U.S. and the Argentine laboratories. ***

9503885迈耶美国-巴西合作科学计划奖资助托马斯·迈耶博士实验室的研究生的旅费。卡茨博士的实验室，图库曼国立大学，图库曼，阿根廷。支持为期两个月的三次访问。反过来，阿根廷方面将支持卡茨博士的实验室的科学家对大学进行为期两个月的三次访问。北卡罗来纳州。一些消耗性研究用品和出版费用也在这项奖励项下得到支助。研究领域是一个重要的领域，因为它既涉及对光化学/物理的基本理解，也涉及更实际的领域，如太阳能转换。这项工作将涉及一系列含有Re(I，II)和Mo(I，0)的混价二聚体的分子内电子转移的研究。这些络合物的设计将使光致Re到Mo电子转移的氧化还原电位可以通过配体修饰来改变。在所有情况下，驱动力都会大于重组能量，因此这一过程发生在马库斯“倒置区域”。这些研究将补充和扩展Meyer关于反转区金属-配体电荷转移的研究，该研究主要集中在单金属配合物上。在业务上，北卡罗来纳州和阿根廷集团的优势将得到有效利用。虽然化合物的设计是共同的责任，但准备工作将在图库曼进行，那里的实验室和人员拥有大量的合成专业知识。然后，这些复合体将被运送到北卡罗来纳州，在那里将使用迈耶高度专业化的激光设备进行光化学实验。为了建立一个连贯的研究团队，有效地结合两个研究小组的个人才华，研究计划包含了美国和阿根廷实验室之间人员交流的详细时间表。***
