This research will extend the University of Denver atlas of high resolution (~0.002 cm-1) balloon-borne infrared solar absorption stratospheric spectra and the corresponding laboratory, ground-based and theoretical studies initiated under previous NSF grants. The major objectives are: 1) To extend the 0.002 cm-1 resolution atlases over additional intervals in the 2.5-30 micron region, by using solar and laboratory spectra already obtained and new spectra anticipated to be obtained in 2005-2008. Many new stratospheric spectral features will be observed and studied. 2) To extend the spectroscopic analysis of specific stratospheric molecules, such as O3, HNO3, ClONO2, COF2, COCl2, HCOOH, NO2, O2, OH, NO and others, from the laboratory and stratospheric spectra. The spectroscopic analysis will include line positions and line intensities for identification and quantification of trace species. Contributions are expected to the field of atmospheric chemistry through atmospheric and solar spectroscopy.This work on theoretical spectroscopy promotes the development of new methods for modeling molecular and atomic structure, leading to the incorporation of new technologies for instrumentation capable of more accurate atmospheric measurements. These studies also continue to have broader impacts on the understanding of planetary and astrophysical spectroscopy, as well as environmental spectroscopy.

这项研究将扩大丹佛大学的高分辨率（~0.002 cm-1）气球载红外太阳吸收平流层光谱图集，以及根据国家科学基金会以前的赠款开展的相应的实验室、地面和理论研究。 主要目标是：1）利用已经获得的太阳光谱和实验室光谱以及预计在2005-2008年获得的新光谱，将0.002厘米-1分辨率的地图集扩展到2.5-30微米区域的更多间隔。 将对许多新的平流层光谱特征进行观测和研究。 2)从实验室和平流层光谱中扩展对特定平流层分子的光谱分析，如O3、HNO 3、ClONO 2、COF 2、COCl 2、HCOOH、NO2、O2、OH、NO等。 光谱分析将包括谱线位置和谱线强度，用于鉴别和定量痕量物质。 预计通过大气和太阳光谱学对大气化学领域作出贡献，这一理论光谱学方面的工作将促进开发模拟分子和原子结构的新方法，从而采用能够更准确地测量大气的仪器新技术。 这些研究还继续对行星和天体物理光谱学以及环境光谱学的理解产生更广泛的影响。
