| Outline of Final Research Achievements |
Estimation of energies and structures of the transition state is a important subject to consider the reaction mechanism. And it would give us an important information for molecular design as well as reaction design and reaction control if we can expect the biradical transition state quantitatively. Since the Broken-symmetry (BS) method would be quite effective method for the biradical reaction mechanism. However, the BS method has a spin contamination error. Our group has developed a method to eliminate the error from the first and second derivatives of the BS energy (AP method). However, a further development was necessary to apply it to the BS transition state. In this regard, we succeeded several points in this project. First, we could combine the semi-empirical method and the AP method. For the purpose, we developed the new parameter of the semi-empirical method especially for the AP method. In addition, we applied those method to binuclear copper(II) complexes.
