| Outline of Final Research Achievements |
In interstellar molecular clouds, elements such as hydrogen, oxygen, carbon, and nitrogen deposit on dust grains, and form various molecules (e.g., H2O, CO, CO2, NH3, CH4, H2CO, CH3OH, and so on). These molecules undergo chemical evolutions to organic molecules through various processes on the surface of dust grains. We investigated the microscopic and macroscopic processes of chemical evolutions in space using various theoretical methods. The members of microscopic group studied basic processes of amorphous materials in molecular clouds (for instance, surface structures, diffusions, and reactions) using molecular simulations. The members of macroscopic group modeled the various reaction processes in molecular cloud (for instance, thermal desorption, grain surface reactions, and so on) using chemical network simulations.
