演 題 | Fascinating World of Theoretical Studies of Chemical Reactions -From Gas Phase Reactions to Catalysts, and Enzymatic Reactions- |
講 師 | 諸熊 奎治 先生 (京都大学福井謙一記念研究センター・シニアリサーチフェロー)) |
概 要 | The chemical reaction that creates, destroys, reorganizes chemical bonds to produce new compounds is the most important subject of chemistry. I have been absorbed by this fascinating world of chemistry from the beginning of my career fifty years ago. Theoretical/computational studies have come a
long way and are now playing the central role in understanding the mechanism
and dynamics of chemical reactions and in helping designing more useful
chemical reactions and catalysts. The theory can study not only the reaction
of the ground state of molecules in gas phase but also reactions of excited
electronic states as well complicated reactions of complex molecular
systems. The information theoretical/computational studies can provide is
often complementary to the information experimental studies provide, and
research on chemical reactions is becoming impossible without strong
collaboration between theorists and experimentalists.
In the present talk, I will discuss some of our recent studies of chemical
reactions. We have developed the Global Reaction Route Mapping (GRRM)
strategy for automatic exploration of reaction pathways of complex molecular
systems [1]. The ADDF (anharmonic downward distortion following) and the
AFIR (artificial force induced reaction) methods have been used for
determination of not only energy minima and saddle points on the potential
energy hypersurfaces but also minima and saddle points on the conical
intersection and crossing seam hypersurfaces. I will discuss the methods and
applications to several reaction systems, including photodissociation
reactions, catalytic reactions and enzymatic reactions. I will also discuss
other theoretical studies of mechanism and dynamics of chemical reactions of
complex systems. |

演 題 | Is Interstellar Medium (ISM) Chemistry the beginning of prebiotic Chemistry? How are the Complex Organic Molecules (COMs) formed in the ISM ? |
講 師 | Prof. Fabien Borget (仏国・マルセイユ大学) |
概 要 | In this seminar, I will show how simulate the ISM conditions in a lab.
Then, using a mechanistic approach, I will show how primitive ices can yield complex molecules.
I will focus especially on the formation of reservoir molecules that can form, in specific conditions, the elementary molecules of life, called prebiotic molecules. |
