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.

在过去几年中，我们的工作重点是自由基和分子离子的亚毫米波光谱研究，特别是天体物理和大气化学方面的研究。光谱系统的高灵敏度、高精度和高效率的数据采集是成功寻找自由基和离子的关键因素。为了实现这一目标，我们采用了俄罗斯制造的后向波振荡器作为辐射源。采用双锁相环稳定了振荡频率。以下是对主要结果的总结，并将已发表的有关这些结果的完整报告作为附录附上。与JEM/SMILES小组的合作已经得到了衡量。这些项目也与喷气推进实验室小组合作进行。本项目期间取得的主要成果主要集中在以下几个方面：(1)不稳定物质的光谱分析(2)等离子体CVD工艺中放电等离子体反应中间体的鉴定。(3)对与地球大气化学有关的分子进行精确的压力扩展测量。
