Abstract |
Over the years, we have been developing a method which could reveal the dynamical events of chemical reactions. Observing chemical reactions in real time is one of the ultimate goals of physical chemistry. Experimentally, a great deal of time-resolved spectroscopies as well as ultrafast X-ray have been developed to observe the events. Our initial attempts were the introductions of quantum theories to the molecular dynamics,[1,2] which has been the basic foundation for the further developments. Currently, we are developing a way to study fast chemical reaction dynamics including the “nonadiabatic processes” of internal conversions as well as intersystem crossings. In this talk, we introduce these on-going projects focusing on our new linear response theory for better descriptions of degenerate (or near-degenerate) electronic states.
