Abstract:Understanding the natures and rules of chemical reactions is an important direction of research in chemistry. The chemical dynamics is a discipline which studies the dynamical natures and rules of various chemical reactions from macroscopic reaction rates to the microscopic mechanisms on atomic, molecular, and quantum state levels. The exploration and learning of the dynamical nature in the chemical reaction play a vital role in the development of chemistry discipline. Over the past decades, there have been a series of achievements in the research of chemical dynamics, such as the revelation of the nature of chemical reaction, the clarification of the mechanism of ozone depletion, the development of chemical lasers, the discovery of C60 molecule, etc. This program is aimed to study the dynamical mechanisms of several important chemical processes with depth and detail, revealed the fundamental rules of chemical dynamics on the atomic and molecular level with quantum-state resolved resolution, by developing and using the international advanced experimental techniques and high-precision dynamic theories. We will focus on the development of chemical dynamics theory and work on the fundamental and original research about several front dynamical subjects. These front subjects include the reaction dynamics on the polyatomic system, combustion chemical kinetics, reaction dynamics of cluster and surface, the dynamics of excited state molecule, photochemical dynamics on surface, and new methodologies for chemical cynamics and kinetics. According to the research content there are 6 subjects in this program, which are organized and implemented by the chief scientist and undertaken by Dalian Institute of Chemical Physics, CAS., University of Science and Technology of China, Fudan University, Institute of Chemistry, CAS., Tsinghua University, Peking University, Nanjing University, and Beijing Normal University respectively. The research team consists of 28 people, including one academician of CAS and 27 professors. We will publish 400 SCI papers, among which 40 papers in high-end academic journals such as JACS, PRL, and endeavour to publish our research results in Science or Nature. The budget of this program is 39.6 million RMB yuan.
