Outline of Final Research Achievements

Revealing a diversity of chemical composition among molecular clouds and its origin is one of important issue to be addressed in the starformation studies. In this research, we have explored the diversity by observation toward molecular clouds in our Galaxy and nearby galaxies with radio telescopes. From the observation with IRAM 30 m, Mopra 22 m, and NRO 45 m radio telescopes, we found that the chemical compositions are similar to each other among molecular clouds in our Galaxy and nearby galaxies, which possess similar elemental abundance of heavy atoms. In addition, we have conducted high angular resolution observation toward nearby galaxy M83 and NGC 3627 with ALMA. In NGC 3627, we fond that abundance of CH3OH is enhanced by interaction between the molecular clouds. Our results give insights into the starformation process in the galaxies.
