More than 750 publications.

Important Contributions:

  • Development and Application of the ONIOM Method.. Development of a multi-layered method called ONIOM, a method integrating different levels of molecular orbital methods and molecular mechanics methods for accurate theoretical calculations for large molecular systems.
  • Studies of Molecular Interactions. The first ab initio calculation and prediction of the structure of water dimer in 1968. Development of the energy decomposition scheme for analysis of intermolecular interactions, including hydrogen bonding, electron donor-acceptor interaction, and metal-ligand interaction.
  • Studies of Potential Energy Surfaces for Chemical Reactions. The first application of ab initio gradient to the transition state and the intrinsic reaction coordinate. Studies of potential surfaces and elucidation of reaction mechanisms, in both ground and excited states. Recent development of methods for automatic search of reaction pathways.
  • Structure, Interactions and Reactions of Nano Structures. Theoretical studies of the mechanism of formation of carbon nanostructures as such fullerenes, carbon nanotubes and graphenes.
  • Studies of Structure and Reactions of Transition Metal Complexes. The first determination of the transition state for elementary organometallic reactions. The first to find the electronic origin of agostic interaction. The first to calculate the potential energy profile of an entire catalytic cycle. Major contributions to elucidation of reaction mechanisms of many organometallic reactions and homogeneous catalyses as well as metalloenzyme reactions.
  • Structure and Reactions of Proteins in Both Ground and Excited Electronic States. Mechanism of reaction of metalloenzyme systems with active site and full protein models. Mechanism and dynamics of photochemical processes in biomolecular systems, such as green fluorescent proteins and luciferase. Spectral tuning mechanism of visual pigments.
