从GBT PRIMOS巡天观测中探测到星际乙亚胺（CH3CHNH）
The Detection of Interstellar Ethanimine (CH3CHNH) from Observations taken during the GBT PRIMOS Survey
摘要：
我们已经进行了反应产物筛选测量，使用宽带旋转光谱，以确定实验室光谱和绿岸望远镜PRIMOS射电天文学调查光谱在人马座B2北（Sgr B2（N））之间的旋转过渡匹配。在CH 3CN和H2S的放电中产生的分子的宽带旋转光谱包含了几个与PRIMOS调查中未识别的特征相匹配的频率，这些特征没有基于标准射电天文学光谱目录的分子分配。这些转变中的几个被分配到乙亚胺的E-和Z-异构体。全球拟合的旋转光谱的这些异构体在8至130 GHz的范围内已经进行了异构体使用以前公布的毫米波光谱测量和微波测量的当前研究。讨论了E-乙亚胺和Z-乙亚胺可能的星际化学形成途径。乙醇胺的检测是重要的，因为它可能在丙氨酸的形成中起作用-遗传密码中的二十种氨基酸之一。
英文摘要：
We have performed reaction product screening measurements using broadband rotational spectroscopy to identify rotational transition matches between laboratory spectra and the Green Bank Telescope PRIMOS radio astronomy survey spectra in Sagittarius B2 North (Sgr B2(N)). The broadband rotational spectrum of molecules created in an electrical discharge of CH3CN and H2S 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 to 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.
