| Outline of Final Research Achievements |
We have constructed a chemical reaction network toward synthesis of glycine, the simplest amino acid, in interstellar space by comprehensive investigation of previous researches, and have identified several key molecules for synthesizing glycine. To date, most of these species are impossible to explore by radio-astronomy due to lack of relevant spectroscopic information. In this study we tried to observe rotational spectra of Aminoacetonitrile, Hydantoin, and Aminomethanol in the millimeter-wave to sub-millimeter-wave frequency region, all of which can be regarded as direct precursors of glycine in the chemical network. Spectroscopic characterization for former two species in their vibrational ground and excited states has been successfully made, and their molecular constants are accurately determined. Line frequency catalogues for these molecules have been established for astronomical observation with whole ALMA observation bands.
