In this Experimental Physical Chemistry project funded by the Division of Chemistry, Prof. Coe (Ohio State University) will build a novel apparatus in which a molecular beam of positively charged, solvated ions is gently merged with a similar beam of negatively charged ions. Recombination will be monitored by detecting fast moving neutral products. This will permit production of solvent-separated ion pair clusters, and will lead to elucidation of step-wise solvation energies of strong electrolytes.%%% Reactions of charged species in solution lie at the heart of many chemical reactions, but very little hard information has been available about the detailed role of intervening solvent in influencing the course of the reaction. Prof. Coe (Ohio State University) will address this question by building an apparatus which will make it possible for the first time to determine how many solvent molecules there must be around the reacting species in order to keep positively charged materials from reacting immediately with negatively charged species. This will help to answer the more general question of how many molecules are needed to define what chemists mean by a solution of one substance in another.

在这个实验物理化学项目资助的 科教授（俄亥俄州州立大学）将在 建造一种新的装置， 带电的溶剂化离子与类似的离子束轻轻地合并， 带负电荷的离子将由以下人员监测澄清情况： 检测快速移动的中性产品。这将允许 生产溶剂分离的离子对簇，并将 从而阐明了强溶剂化能 电解质。% 带电物质在溶液中的反应是 许多化学反应，但很少有硬信息 关于介入溶剂的详细作用， 影响反应进程。Coe教授（俄亥俄州 州立大学）将通过建立一个 这将是第一次有可能， 确定有多少溶剂分子必须围绕 反应物质以保持材料带正电 与带负电荷的物质立即反应。这 将有助于回答一个更普遍的问题， 需要分子来定义化学家所说的溶液 一种物质在另一种物质中。
