| 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, which 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 on vibrational relaxation and reaction dynamics were investigated for chemical reactions in hydrogen liquid.
Two international conferences in addition to five domestic conferences were held at Kyoto in 1999 and 2001.
In this year (2002) we summarize the report of whole three years activities (1998-2001) which contains more than 200 pages. Members of this research projects have been invited to many (more than 100) international conferences. More than 260 papers were published under this project. We also invited several distinguished foreign scientists to pursue the cooperative works.
