Analysis of Near-Infrared ILS Spectroscopy for Planetological Application

AST 9618704近红外离子液体光谱在行星学中的应用分析。乔治·阿特金森博士和乔纳森·卢宁博士将在实验室使用腔内激光光谱(ILS)来检测和表征1-3微米波长范围内的微弱吸收特征，这些特征来自与行星大气相关的分子，如一氧化碳、氮气和甲烷。与其他表征分子线参数的方法相比，ILS技术有很大的优势：1)它可以获得非常大的有效路径长度，而不需要很大的物理路径长度和/或气体体积；2)现在可以研究其他技术无法获得的弱特征。要检查的实验条件重现了记录天文观测数据的条件。定量模拟天文观测数据的机会来自于ILS技术可以使用的极高的探测灵敏度和多功能性。=

AST 9618704 Analysis of Near-Infrared ILS Spectroscopy for Planetological Application. Drs. George Atkinson and Jonathan Lunine will use intracavity laser spectroscopy (ILS) in the laboratory to detect and characterize weak absorption features in the 1-3 micron wavelength range from molecules associated with planetary atmospheres, such as carbon monoxide, nitrogen, and methane. The ILS technique presents a great advantage over other methods of characterizing molecular line parameters: 1) it achieves very large effective pathlengths without large physical pathlengths and/or volumes of gases; and 2) weak features that are inaccessible to other techniques can now be studied. The experimental conditions to be examined reproduce those under which astronomical observational data were recorded. The opportunity to quantitatively mimic astronomical observational data is derived from the extremely high detection sensitivity and versatility with which ILS techniques can be used. =========================
