| Outline of Final Research Achievements |
The purpose of this study is analysis between molecular structures and their formation processes for organic astromaterials from molecular clouds to protoplanetary system. A novel liquid chromatography-mass spectrometer system with ultra-high mass resolution has been developed. Mass spectra with ultra-high mass resolution of solved organic matter from carbonaceous meteorites and analog organics synthesized under molecular cloud conditions were obtained. These organic astromaterials were classified into several organic homologues from the spectrum patterns of their high precision molecular mass. These results show that aldehyde and ammonium are candidates of novel molecular marker and functional group linking between molecular cloud molecules and organic molecules in meteorites.
