The discovery of more than 200 gas-phase chemical compounds in interstellar space has led to the speculation that this nonterrestrial synthesis may play a role in the origin of life. These identifications were possible because of laboratory spectroscopy, which provides the molecular fingerprints for astronomical observations. Interstellar chemistry produces a wide range of small, organic molecules in dense clouds, such as NH2COCH3, CH3OCH3, CH3COOCH3, and CH2(OH)CHO. Carbon (C) is also carried in the fullerenes C60 and C70, which can preserve C-C bonds from circumstellar environments for future synthesis. Elusive phosphorus has now been found in molecular clouds, the sites of star formation, in the molecules PO and PN. Such clouds can collapse into solar systems, although the chemical/physical processing of the emerging planetary disk is uncertain. The presence of molecule-rich interstellar starting material, as well as the link to planetary bodies such as meteorites and comets, suggests that astrochemical processes set a prebiotic foundation.Expected final online publication date for the Annual Review of Physical Chemistry, Volume 75 is April 2024.

来自天文观测和实验室光谱学的生命起源前天体化学

在星际空间中发现的 200 多种气相化合物引发了人们的猜测，即这种非陆地合成可能在生命的起源中发挥着作用。这些鉴定之所以成为可能，是因为实验室光谱学为天文观测提供了分子指纹。星际化学会在稠密的云层中产生各种小有机分子，例如 NH2科赫3,CH3奥赫3,CH3酷奇3，和CH2(OH)CHO。富勒烯 C 中也携带碳 (C)60和C70，它可以保留星际环境中的 CC 键以供将来合成。现在，人们在分子云（恒星形成的场所）的 PO 和 PN 分子中发现了难以捉摸的磷。尽管新兴行星盘的化学/物理过程尚不确定，但此类云可能会塌陷到太阳系中。富含分子的星际起始材料的存在，以及与陨石和彗星等行星体的联系，表明天体化学过程奠定了生命起源的基础。《物理化学年度评论》第 75 卷的预计最终在线出版日期是 4 月2024 年。请参阅 http://www.annualreviews.org/page/journal/pubdates 了解修订后的估计。
