Submillimeter-wae Investigations of Reaction Intermediates Relevant to Interstellar and Atmospheric Chemistry

在过去的几年里，我们的工作集中在自由基和分子离子的亚毫米波光谱研究上，特别是对天体物理和大气化学感兴趣的研究。光谱仪系统的高灵敏度、高精度和高效率的数据采集是成功寻找自由基和离子的最关键因素。为了实现这一目标，我们使用了俄罗斯制造的反向波振荡器作为辐射源。采用双锁相环稳定了振荡频率。以下是主要成果的摘要，已发表的关于这些成果的完整报告将作为附录附上。已经衡量了与正义与平等运动/微笑小组的合作。这些项目也是与喷气推进实验室小组合作进行的。在本项目期间取得的主要成果主要在以下方面：(1)不稳定物种的光谱分析(2)用于等离子体CVD过程的放电等离子体中反应中间体的鉴定。(3)与地球大气化学有关的分子的精确压力加宽测量。

During the past several years, out effort was focused on submillimeter-wave spectroscopic studies of free radicals and molecular ions, in particular, of astrophysical and atmospheric chemical interests. Very high-sensitivity, high-precision, and high efficiency of data acquisition of a spectrometer system are the most crucial factors for successful search of free radicals and ions. To achieve this goal, we employed Russian-made backward-wave oscillators as radiation sources. The oscillation frequencies have been stabilized by using a double phase-lock loop. Below major results are summarized and full report already published on these results will attached as Appendices. The collaboration with the JEM/SMILES group has been measured. These projects are also pursued in collaboration with the JPL group.Major achievements obtained during this project term are mainly in the following areas: (1)Spectroscopy of unstable species (2)Identification of reaction intermediates in discharge plasma used for plasma CVD processes. (3Precise pressure broadening measurements of molecules relevant to the Earth's atmospheric chemistry.
