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

小行星9317612 太阳系和宇宙气体光吸收截面的原位测量。 吴博士和他的合作者已经成功地进行了高分辨率的实验室测量，低温和室温下存在于太阳系和宇宙气体中的几种分子的光吸收截面。 他们将康廷这项研究，将其应用于测量的横截面的4 PG系统，卡梅隆带，潜在的禁戒跃迁和伪连续的CO和横截面的氨和几个重要的碳氢化合物，包括丙二烯，甲基乙炔，甲基乙烯，环丙烷，二乙炔，和三乙炔，从各自的吸收阈值到1060埃。 在类似于现实行星大气中发现的条件下，将研究诸如分子氢和氮等扰动物对感兴趣的行星的压力影响。

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.
