项目摘要
This U.S.-Hungarian research project between Tamas Baer of the University of North Carolina, Chapel Hill, and Balint Sztaray and Laszlo Szepes of Eotvos University, Budapest, will study the dissociation energies and dynamics of energy-selected ions. They intend to determine accurate ionization and dissociation energies with techniques using threshold photoelectron photoion coincidence (TPEPICO) mass spectroscopy and photoelectron spectroscopy. By combining solution and gas phase bond energies the team expects to learn about solvation energies.The Budapest group will contribute expertise in the synthesis and reactions of organometallic complexes as well as in measuring photoelectron spectra of low vapor pressure samples. The Chapel Hill group's expertise in TPEPICO will be employed to determine dissociation limits for metal ligands. Results should produce new accurate data on the heats of formation and bond energies. This would enhance our ability to develop models and apply statistical theory of unimolecular decay to a broad range of complex molecules. Success could help define catalytic properties of molecules with applicability in a variety of synthetic approaches.This chemistry project fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Central Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence. Broader impacts include the introduction of U.S. students to the international research community through work at the Hungarian institution and direct involvement in current thermochemical research and application of spectroscopy techniques.
这个美国-位于查佩尔山的北卡罗来纳州大学的塔马斯·贝尔和位于布达佩斯的奥特沃斯大学的巴林特·斯塔雷和拉斯洛·塞佩斯之间的匈牙利研究项目将研究能量选择离子的离解能和动力学。 他们打算使用阈值光电子光离子符合(TPEPICO)质谱和光电子能谱技术来确定准确的电离能和离解能。 通过结合溶液和气相键能,该团队希望了解溶剂化能。布达佩斯小组将在有机金属配合物的合成和反应以及测量低蒸汽压样品的光电子光谱方面提供专业知识。 查佩尔山小组在TPEPICO方面的专业知识将用于确定金属配体的解离极限。 结果应该产生新的准确数据的形成热和键能。这将增强我们开发模型的能力,并将单分子衰变的统计理论应用于广泛的复杂分子。该化学项目的成功将有助于确定分子的催化性能,并适用于各种合成方法。该化学项目通过使美国和中欧的专家联合收割机互补人才并在共同感兴趣和能力强的领域共享研究资源,实现了推进科学知识的计划目标。 更广泛的影响包括通过在匈牙利机构工作将美国学生介绍给国际研究界,并直接参与当前的热化学研究和光谱技术的应用。
