Thermochemistry of Metal-Ligand Bonds (Singly and Multiply Charged) and Protonated Peptides

该奖项由化学系化学结构、动力学和机理A(CSDM-A)计划资助，犹他大学化学系的Peter Armentrout教授和研究生研究人员正在非常明确的系统中研究带电物种(离子)与中性分子的反应性。从这些实验中，他们获得了关于反应的能量学的信息(热化学)以及关于这些反应发生的速度的信息(动力学)。在Armentrout实验室接受教育的学生将接受各种技术职业的培训。除了他的科学工作，阿门特劳特教授还通过他在犹他大学的圣诞节法拉第讲座接触到大量的公众。阿门特劳特和他的研究生将利用阿门特劳特集团的制导离子束质谱仪(GIBMS)进行一系列实验，探索过渡金属阳离子与中性反应伙伴的反应性。研究将包括：(1)过渡金属阳离子反应性的具体状态测量，重点是定量评估自旋-轨道对化学反应活性的影响；(2)多电荷金属离子的溶剂化能的测量，包括电荷分离通道势能面的显式量化，强调具有环境和生物学意义的重要例子；(3)继续研究与生物有关的分子与金属阳离子和质子化体系的结合；(4)开展理论工作，以补充(1)-(3)中的所有实验研究。在阿门特劳特教授的实验室接受培训的学生已经进入了学术界和工业界。

In this award, funded by the Chemical Structure, Dynamics and Mechanisms A (CSDM-A) Program of the Division of Chemistry Professor Peter Armentrout of the Department of Chemistry of the University of Utah and graduate student researchers are studying the reactivity of electrically-charged species (ions) with neutral molecules in extraordinarily well-defined systems. From these experiments, they obtain information about the energetics of reactions (thermochemistry) as well as information about the speed with which these reactions take place (kinetics). Students educated in the Armentrout laboratory will be trained for a wide variety of technical careers. Besides his scientific work, Prof. Armentrout reaches large numbers of members of the public through his Christmas Faraday Lectures at the University of Utah.Prof. Armentrout and his graduate students will be carrying out a series of experiments, exploring the reactivity of transition metal cations with neutral reaction partners, using the Armentrout group's guided ion beam mass spectrometer (GIBMS) instruments. Studies will include: (1) state-specific measurements of transition metal cation reactivity, with an emphasis on quantitative evaluation of spin-orbit effects on chemical reactivity; (2) measurement of solvation energies of multiply charged metal ions, including explicit quantification of the potential energy surface for charge separation channels, emphasizing environmentally and biologically important examples; (3) continued studies of binding of biologically-relevant molecules to metal cations and protonated systems; and (4) theoretical work to complement all of the experimental studies in (1) - (3). Students receiving training in Prof. Armentrout's laboratory have gone on to positions in academia and industry.
