Mechanistic Organic Chemistry of Relevance to the Insterstellar Medium

这项研究的重点是识别、表征和检查星际空间中有机分子的反应性。已知或可能存在于星际空间的物种将在实验室的低温基质中产生，并通过各种光谱技术进行表征。实验室结果将与射电天文搜索相关联，以确定星际云中的新物种，以及弥漫星际带的载体。这项研究将向研究生和博士后介绍低温基质分离技术、分离物种的光谱特征以及这些技术的独特跨学科应用。有了这个续展奖，有机和高分子化学计划支持威斯康星大学化学系罗伯特·麦克马洪教授的研究。麦克马洪教授的研究将解决有关已知或假设存在于星际空间的反应性有机碎片的性质和化学问题。被认为存在于星际空间的中间体将在实验室中制备，通过光谱指纹采集，并将光谱数据与射电天文数据进行比较，以确定它们在星际云和漫射星际带中的存在，并确定存在的其他物种。麦克马洪教授的教育活动将包括培养研究生和博士后。

This research focuses on identifying, characterizing and examining the reactivity of organic molecules that occur in interstellar space. Species known, or likely to exist in interstellar space will be generated in low temperature matrices in the laboratory and characterized by a variety of spectroscopy techniques. Laboratory results will be correlated with radioastronomical searches to identify new species in interstellar clouds, and the carriers of diffuse interstellar bands. The research will introduce graduate and postdoctoral students to low-temperature matrix-isolation techniques, spectroscopic characterization of the isolated species, and a unique interdisciplinary application of these techniques. With this Renewal award, the Organic and Macromolecular Chemistry Program supports the research of Professor Robert McMahon of the Department of Chemistry at the University of Wisconsin. Professor McMahon's research will address questions regarding the nature and chemistry of the reactive, organic fragments known, or postulated to exist in interstellar space. Intermediates thought to be present in interstellar space will be prepared in the laboratory, spectroscopically fingerprinted, and the spectral data compared with radioastronomical data to establish their presence in interstellar clouds and diffuse interstellar bands, and to identify other species present. Professor McMahon's educational activities will include the training of graduate and postdoctoral students.
