Measurements of Photoabsorption Cross Sections of Solar System and Cosmic Gases Under In-Situ Conditions

9317612原位条件下太阳系和宇宙气体光吸收截面的吴测量。吴博士和他的合作者已经成功地在实验室测量了太阳系和宇宙气体中存在的几个分子的高分辨率、低温和室温的光吸收截面。他们将继续这项研究，将其应用于测量4PG系统的截面、卡梅隆能带、潜在的禁带跃迁和CO的伪连续谱，以及从各自的吸收阈值到1060埃的氨和几种重要碳氢化合物的截面，包括丙烯、甲基乙炔、甲基乙烯、环丙烷、二乙炔和三乙炔。将在类似于现实行星大气的条件下研究分子氢和氮等扰动对感兴趣的流产者的压力效应。

9317612 Wu Measurements of Photoabsorption Cross Sections of Solar System and Cosmic Gases Under In-Situ Conditions. Dr. Wu and his collaborators have successfully performed laboratory measurements of high resolution, low- and room-temperatuare photoabsorption cross sections of several molecules present in Solar System and cosmic gases. They will contine this research by applying it to the measurement of the cross sections of the 4PG system, Cameron bands, the underlying forbidden transitions and the pseudo-continuum of CO and to the cross sections of ammonia and several important hydrocarbons including Allene, Methyl Acetylene, Methyl Ethylene, Cyclopropane, Diacetylene, and Triacetylene, from their respective absorption thresholds to 1060 Angstroms. The pressure effects of perturbers such as molecular hydrogen and nitrogen on the aborbers of interest will be studied under conditions similar to those found in realistic planetary atmospheres.
