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

在有机动力学计划的支持下，帕克博士将获得决定有机自由基离子和双电荷离子在溶液中反应活性的因素的详细基础知识。他的方法利用为等键反应建立的关系，直接从可逆的电极电位测量中获得各种反应的热力学数据。由此得到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中相对键强度的知识的新反应。有机自由基离子是活性物种，除了具有电荷外，还具有未配对的电子。帕克博士已经开发出一种方法，可以测定这些物种和双电荷离子中的键离解能。这反过来将为确定通过中间自由基离子和双电荷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，很可能导致对这些活性中间体的化学更好的理解。

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.
