Analysis of Near-Infrared ILS Spectroscopy for Planetological Application

近红外ILS光谱在行星学中的应用分析。Drs。乔治·阿特金森（George Atkinson）和乔纳森·鲁宁（Jonathan Lunine）将在实验室中使用腔内激光光谱学（ILS）来探测和表征与行星大气相关的分子（如一氧化碳、氮和甲烷）在1-3微米波长范围内的弱吸收特征。与其他表征分子线参数的方法相比，ILS技术具有很大的优势：1)它可以实现非常大的有效路径长度，而无需大的物理路径长度和/或气体体积；2)其他技术无法达到的弱特征现在可以被研究。要检查的实验条件再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. =========================
