U.S.-Norway Cooperative Research: Investigations of Core-Ionization Energies, Acidities, and Related Chemical Properties

目标和与项目目标的相关性：该推荐奖将允许俄勒冈州立大学的T. Darrah Thomas博士和他的研究助理Michele Siggel博士与挪威特罗姆瑟大学的Leif J. Saethre博士合作。他们将研究依赖于分子接受电荷能力的化学过程。有两个因素影响这种能力：(1)中性分子中的电荷分布，它在感兴趣的位置建立了一个或多或少有利于接受电荷的电势，(2)在电荷添加后价电子重新排列的能力，从而为添加的电荷创造了更有利的环境。拟议的研究将试图确定这两个因素在各种化学有趣的系统中的相对重要性。这项研究将结合测量核心电离能、俄歇动能、气相酸度以及理论计算。托马斯博士开发了世界上最杰出的电子能谱实验室之一。Saethre博士过去曾与Thomas博士的团队合作，这个项目是他们富有成效的研究历史的延续。挪威的研究小组实力雄厚，特别是项目所需的理论工作，并且拥有良好的研究和计算设施。这项研究的预期结果可能会增加对基本化学性质的理解。因此，该项目有助于实现美国国家科学基金会与西欧合作科学项目的一个重要目标，即通过将来自美国和欧洲的具有相似研究兴趣并希望从事互利研究合作的科学家聚集在一起，促进科学进步。这笔奖金将用于支付美国首席研究员及其研究小组成员的交通和生活费用，以及通信和运输费用。预计赛斯特医生会回访。提案优点：合作的美国和外国研究人员因其先前的研究成就而受到尊重，并且这项拟议的研究将对科学知识做出重大贡献，这是一个非常好的前景。美国首席研究员是一位受人尊敬的高产科学家。他的外国同事也在这个领域进行重要的研究。工作计划合理，预算合理。两个研究小组都将为该项目做出贡献，并将从合作中获益良多。挪威政府也通过挪威工业和科学研究理事会和挪威马歇尔计划为该项目提供支持。资助：该奖项不会重复其他资助。主要研究者获得美国国家科学基金会化学部实验物理化学计划的项目支持，批准号为CHE-8613418和CHE-8313251。这项建议的INT奖将资助这些研究项目中的第一个项目增加一个重要的国际层面。

Objectives and Relevance to Program Objedtives: This recommended award would allow Dr. T. Darrah Thomas, Oregon State University, and his research associate, Dr. Michele Siggel, to collaborate with Dr. Leif J. Saethre, University of Tromso, Norway. They will study chemical processes that depend on the ability of a molecule to accept charge. Two factors affect this ability: (1) the charge distribution in the neutral molecule, which establishes a potential at the site of interest that is more or less favorable to accepting charge, and (2) the ability of the valence electrons to rearrange after the charge is added, and thus create a more favorable environment for the added charge. The proposed research will try to determine the relative importance of these two factors in a variety of chemically interesting systems. The research will use combined measurements of core ionization energies, Auger kinetic energies, and gas-phase acidities together with theoretical calculations. Dr. Thomas has developed one of the outstanding electron spectroscopy laboratories in the world. Dr. Saethre has worked with Dr. Thomas' group in the past and this project is a continuation of their productive research history. The Norwegian research group is strong, especially for the required theoretical work of the project, and it has good research and computing facilities. The expected results of the research could increase the understanding of fundamental chemical properties. The project thus contributes to an important objective of NSF's cooperative science programs with Western Europe, which is to stimulate scientific progress by bringing together scientists from the U.S. and Europe who have similar research interests and who wish to engage in mutually beneficial research cooperation. Funds from this award would support necessary transportation and subsistence expenses for the U.S. principal investigator and members of his research group, as well as communication and shipping costs. Return visits by Dr. Saethre are anticipated. Merit of Proposal: The cooperating U.S. and foreign investigators are respected for their previous research accomplishments, and there is a very good prospect that this proposed research will lead to a significant contribution to scientific knowledge. The U.S. principal investigator is a respected, productive scientist. His foreign colleague is also carrying out important studies in this field. The work plan is sound and the budget is reasonable. Both research groups will contribute to the project and will benefit significantly from the cooperation. The government of Norway, through the Norwegian Council for Industrial and Scientific Research and the Norwegian Marshall Plan, is also providing support for the project. Funding: This award will not duplicate other funding. The principal investigator receives project support from NSF's Division of Chemistry, Experimental Physical Chemistry Program, Grant Nos. CHE-8613418 and CHE-8313251. This recommended INT award would fund the addition of an important international dimension to the first of these research projects.
