In this Research Program, notifying the multidimensionality of chemically reacting systems, a number of research were executed focusing the following two points : (a) they are time-dependent chemical processes and (b) nonlinear, nonequilibrium and nonstationary processes :(1) The reactive energy transfer mechanism was analyzed by using not only the Fokker-Planck equation for polyatomic molecules but also molecular dynamics (MD) simulation.(2) We explained some typical characteristics in nonequilibrium dynamics by using MD simulation and developed a novel treatment to locate critical points on the free energy hypersurface, i.e., free energy gradient method (FEGM).(3) We investigated the connection between the above method and a model theory based on the Fokker-Planck equation.In the middle of the research term, several results with respect to the reactive energy transfer in solution, were published in the annual meetings of Japan Chemical Society and Pacifichem2000. Further, they were collected and published as several research Articles as described in the following section, i.e., 11 REFERENCE.
