Outline of Final Research Achievements

Strecker reaction is thought to be one of the important pathways for the synthesis of amino acid. Observation of corresponding precursor molecules of the amino acid will give us some clues whether the reaction plays a crucial role in interstellar space or not.
Glycine, the simplest amino acid, can be produced by Strecker reaction, directly from the precursor molecules, which are aminoacetonitrile and methanimine. In the present study, we measured pure rotational spectra of these amino acid precursors and its deuterium, carbon and nitrogen isotopologues in the millimeter-wave to terahertz frequency range, and have determined molecular constants precisely. With these results, the spectral line frequency data of the molecules are now available for astronomical observation with whole ALMA observation bands.
