| Research Abstract |
Group A: Ohno developed a composite natural orbital method to describe the electron correlation effect in molecules, and Hirao proposed a new wave functional theory based on a cluster expansion method for the more accurate description of dissociation processes in molecules. Nakatsuji studied potential energy surfaces of molecules by using a symmetry-adapted cluster expansion method, and I'Haya and Shibuya obtained promising results for electron correlation in linear polyenes, the former working with a modified crystal orbital method and the latter with a higher-order random phase approximation method._*)
Group B: Imamura developed an iterative transfer perturbation method to involve infinitely higher order terms in perturbation expansion and applied it to the estimate of interaction between a polymer and small molecules. Nishimoto analyzed a proton transfer mechanism in excited molecules, Morokuma investigated the potential energy characteristics in chemical reaction processes, and Iwat

a studied the molecular interaction between the Be atom and water. S.Yamabe's main interest was an analysis of photochemical organic reaction pathes by paying attention to the symmetry conservation during chemical reactions. Yamaguchi solved the photochromic problem in the Diels-Alder addition reactin between dienesand singlet oxygen.
Group C: T.Yamabe worked with the tunneling reaction path for the interaction of silicon and water, Adachi investigated the electronic structure of iron-oxide clusters by using the DV-X method, Higuchi calculated the zero-magnetic field hyperfine splitting constants of aromatic compounds, Fujimura analyzed a pre-dissociative mechanism of the van der Waals molecular complexes, Hosoya worked out the spin multiplicity determination for non-alternant hydrocarbons by using the graph theory, and Anno made vibraiton analyzes of benzene in its excited states.
All members realized great results by dint of industry, as was expected.
^*) Aono's endevor by using the propagator theory to find out possibility of organic superconductors was highly recognized. Less
