The broadband rotational spectrum of molecules created in an electrical discharge of CH 3 CN and H 2 S contained several frequency matches to unidentified features in the PRIMOS survey that did not have molecular assignments based on standard radio astronomy spectral catalogs. Several of these transitions are assigned to the E - and Z -isomers of ethanimine. Global fits of the rotational spectra of these isomers in the range of 8-130 GHz have been performed for both isomers using previously published mm-wave spectroscopy measurements and the microwave measurements of the current study. Possible interstellar chemistry formation routes for E -ethanimine and Z -ethanimine are discussed. The detection of ethanimine is significant because of its possible role in the formation of alanine—one of the twenty amino acids in the genetic code.} }
