| Research Abstract |
We have investigated the molecular origin for the complexity and specificity of manybody chemical systems, such as chemical reaction dynamics in liquid phase and biomolecules. The reaction dynamics of those systems involves fluctuations and collective molecular motions. Experimental and theoretical studies have been made how to observe the most important motions leading to the specific reaction, whicn are imbedded in the noise of many particle random motions.. The methods were developed to deal with global nature of the potential energy surfaces (GPES) and the dynamics on this GPES.Highly nonlinear flash photolysis technique, especially in Infra-red region, was developed to deal with the phase space dynamics of the complex systems and Transient Grading technique for detect heat flow in molecular scale and in ultrafast time domain. Reactions of Bacteria rhodopsin and DNA molecules were examined to find our why the specific process always take place in biomolecular reactions. Quantum effects out vibrational relaxation and reaction dynanmics were intvestigated for clemical reactions in hydrogen liquid.
We have held two international conferences in addition to five domestic conferences. There are 70-90 attendants in each conference making stimulating discussions on the each topics provided by the project members and foreign scientists, like Profs. Schulten, Fleming, Onuchic, Brooks, Newton, and many others. Members of this research projects have been invited speakers of many (more than 100) international ccnferences. More than 200 papers were published uuder this projccl. We also invited sevral distinguished foreign scientists to pursue the cooperative works.
