9423848 Goldman The goal of this project is to extend the University of Denver atlas of high resolution (approx. 0.002 cm-1) infrared solar absorption stratospheric spectra and the corresponding laboratory and theoretical studies initiated under previous NSF grants. The currently published high resolution stratospheric atlas covers several intervals between 800 and 1690 cm-1. For each interval, accurate line positions with molecular and atomic identifications are tabulated. Numerous new spectral features have been identified and analyzed. The major objectives of this research are: 1) to extend the 0.002 cm-1 resolution atlases over additional intervals in the 2.5-30um region, mostly with solar and laboratory spectra already obtained, and new spectra anticipated to be obtained in 1994-1997; 2) to extend the spectroscopic analysis of specific stratospheric molecules, such as ozone, nitric acid, chlorine nitrate, carbonyl fluoride, nitrogen dioxide, molecular oxygen, and others, from the laboratory and the stratospheric spectra. The current atlas work and the supporting laboratory studies have contributed significantly to our understanding of atmospheric chemistry through atmospheric and solar spectroscopy, and further contributions are expected.

这个项目的目标是扩展丹佛大学的高分辨率地图集。0.002 cm-1)红外太阳吸收平流层光谱以及相应的实验室和理论研究。目前出版的高分辨率平流层地图集覆盖了800至1690 cm-1之间的几个间隔。对于每个间隔，精确的线位置与分子和原子的识别被制表。许多新的光谱特征已经被识别和分析。本研究的主要目标是：1)将0.002 cm-1分辨率的地图集扩展到2.5-30um区域的额外间隔，其中大部分是已经获得的太阳和实验室光谱，预计在1994-1997年将获得新的光谱；2)从实验室和平流层光谱扩展对特定平流层分子的光谱分析，如臭氧、硝酸、硝酸氯、氟羰基、二氧化氮、分子氧等。目前的地图集工作和支持的实验室研究对我们通过大气和太阳光谱学了解大气化学作出了重大贡献，并期待进一步的贡献。
