In this project, funded by the Chemical Structure, Dynamics, and Mechanisms Program of the Chemistry Division, Professor Peter B. Armentrout of the University of Utah will continue work in the fields of gas-phase organometallic and biological ion chemistry and chemical dynamics. Utilizing mass spectrometric instrumentation, quantitative studies of five interrelated areas of chemical interactions will be performed: electronic state-specific chemistry of transition metal ions; solvation energies of multiply charged metal ions including those of environmental and biological importance; interactions of protons and metal ions with biologically relevant molecules; spectroscopic studies to complement the reactivity studies; and continued development of advanced means to analyze experiments on large and complex systems.Broader impacts resulting from the proposed activity include a continued development of the experimental methods needed to obtain quantitative thermochemical data and the long-range, integrated aspects of establishing a comprehensive thermochemical database. An evolving data analysis program is made freely available to scientific groups around the globe. Educational objectives remain a key component of this research program. Outreach efforts include popular Christmas lectures at the University of Utah.

在这个由化学系化学结构、动力学和机制项目资助的项目中，Peter B教授。犹他州大学的Armentrout将继续在气相有机金属和生物离子化学和化学动力学领域的工作。利用质谱仪器，将对化学相互作用的五个相互关联的领域进行定量研究：过渡金属离子的电子态特定化学;多电荷金属离子的溶剂化能，包括具有环境和生物重要性的金属离子;质子和金属离子与生物相关分子的相互作用;光谱研究，以补充反应性研究;拟议活动产生的更广泛影响包括继续开发获得定量热化学数据所需的实验方法，以及建立综合热化学数据库的长期综合方面。 一个不断发展的数据分析程序免费提供给地球仪的科学团体。教育目标仍然是这项研究计划的一个关键组成部分。 外联工作包括在犹他州大学举办受欢迎的圣诞讲座。
