Molecular theory of solvent effects an chemical reactions

包括原子交换在内的化学反应的主要驱动力是电子结构的变化。然而，如果反应发生在溶液中，溶剂效应就成为决定反应活性和反应速率的另一个重要因素。本项目提出的研究内容是结合主要研究者提出的理论，建立一种新的溶液化学反应理论。化学反应不仅发生在散装溶液中，也发生在与电极和酶的交界面上。近年来，汽液界面和液液界面也成为重要的反应场。因此，我们将研究范围扩展到此类溶液界面的相关问题，并发展了气液分离和液液相分离的新理论。这些研究发表在53篇科学期刊上。研究对象分为以下五类。(1)溶液中的电子结构、化学反应和溶剂化电子。(2)生物分子和蛋白质折叠的稳定性。(3)溶液中的动力学和弛豫过程。(4)界面处溶液的统计力学。(5)分子液体、相变和相分离统计力学的发展。研究结果也发表在以下著作中：f.h hirata主编，“分子理论的溶剂化”，Kluwer-Springer学术，2003。

Primary driving force of chemical reactions including exchange of atoms is the change in electronic structure. However, if a reaction takes place in solution, solvent effect becomes another important factor to determine both the reactivity and reaction rate. The study proposed in the project is to build a new theory of chemical reactions in solution by combining the theories which have been proposed by the principal investigator.Chemical rections take place not only in bulk solutions but also at such interfaces with electrodes and enzymes. Recently, vapor-liquid and liquid-liquid interfaces have been also realized as important reaction fileds. Therefore, we extended our study to the problems related to such solution interfaces, and developed new theories concerning vapor-liquid and liquid-liquid phase separation. Those studies are published in 53 papers in scientific journals. The research subjects are classified into the following five categories.(1)The electronic structure, chemical reaction and solvated electrons in solutions.(2)Stability of biomolecules and protein folding.(3)Dynamics and relaxation processes in solutions.(4)The statistical mechanics of solution at interfaces.(5)Development of the statistical mechanics of molecular liquids, and of phase transition and phase separation.The results of the study are also published in the following book.F.HIRATA Ed., "Molecular Theory of Solvation," Kluwer-Springer Academic, 2003.
