Research Abstract

The purposes of the research project, "Theory of Chemical Reactions : Theoretical and Computational Approach", are (1) Exploration of the reaction dynamics of the excited molecules, (2) Quanitative prediction of the reaction paths, reaction intermediates and transition states, and inquiry of the inevitability of chemical reactions, (3) Theoretical analysis of the homogeneous and inhomogeneous catalysis reaction mechanism, and (4) Quantitative exploration of chemical reactions in solution. To achieve the targets, we organized four research projects ; A01 : Many-electron theory of molecules, A02 : Electronic theory of chemical reactions, A03 : Theory of chemical reaction dynamics, and A04 : Theories of chemical reactions in molecular assemblies.
In last four years, our members published more than 900 papers in the international journals, and gave more than 130 invited talks in the international scientific meetings. During the research project, we are proud of the great advance we have made in the theory of chemical reactions, both in the purely theoretical and conceptional study and in the applied and computational study. In addition, in these years, the number of the research groups of the theoretical chemistry in Japan has substantially increased, and the research activity in this field has been very high. As a result of the present research project, we successfully established a network of the research groups related to the chemical reactions, not only among theoretical groups but also with the experimental group. This project has demonstrated the importance of theoretical approaches in studying the chemical reactions and the need of more emphasis on establishing the theoretical groups in Departments related with chemical study in the Universities and research Institutes.
