The Reactions and Energetics of Organic Radical Ions and Doubly Charged Ions in Solution

在有机动力学项目的支持下，帕克博士将获得决定有机自由基离子和双荷离子在溶液中反应性的因素的详细基础知识。他的方法利用等速反应的关系，直接从可逆电极电位测量中获得各种反应的热力学数据。由此获得的热力学数据将允许预测键离解能，并可用于建议基于自由基离子和双电荷离子相对键强度的新反应。有机自由基离子是一种活性物质，除了带有电子电荷外，还具有一个不成对的电子。帕克博士开发了一种方法，可以测定这些物质和双电荷离子的键解能。反过来，这将为确定通过中间自由基离子和双带电离子进行的各种反应的能量学提供一个数据基础。由此获得的信息将提供基本的新知识，可能导致对这些反应性中间体化学的更好理解。

With support from the Organic Dynamics Program, Dr. Parker will obtain detailed fundamental knowledge of the factors that determine the reactivity of organic radical ions and doubly charged ions in solution. His approach utilizes relationships developed for isodesmic reactions to obtain thermodynamic data for a variety of reactions directly from reversible electrode potential measurements. The thermodynamic data thereby obtained will permit prediction of bond dissociation energies and can be used to suggest new reactions that are based upon knowledge of relative bond strengths in radical ions and doubly charged ions. %%% Organic radical ions are reactive species that possess an unpaired electron in addition to an electronic charge. Dr. Parker has developed a method that will permit bond dissocia- tion energies in these species and in doubly charged ions to be determined. This, in turn, will provide a data base for determining the energetics of a variety of reactions that proceed via intermediate radical ions and doubly charged ions. The information thereby obtained will provide fundamental new knowledge that is likely to lead to improved understanding of the chemistry of these reactive intermediates.
