Rotational spectroscopy at millimeter wavelengths is a powerful means of investigating the chemistry of dense interstellar clouds. These regions can exhibit an interesting complement of gas phase molecules, including relatively complex organics. Here we report the tentative first astronomical detection of aziridine (ethylenimine), the possible detection of propenal (acrolein), and upper limits on the abundances of cyclopropenone, furan, hydroxyethanal (glycolaldehyde), thiohydroxylamine (NH2SH), and ethenol (vinyl alcohol) in various interstellar clouds.
毫米波波段的转动光谱学是研究致密星际云化学组成的有力手段。这些区域可能存在有趣的气相分子组合，包括相对复杂的有机物。在此，我们报告了氮丙啶（乙烯亚胺）首次可能的天文探测结果、丙烯醛可能的探测结果，以及在各类星际云中环丙烯酮、呋喃、羟基乙醛（乙醇醛）、硫代羟胺（NH₂SH）和乙烯醇丰度的上限。
