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.

在过去的几年中，OUT的努力集中在自由基和分子离子，特别是天体物理和大气化学兴趣的亚毫米波光谱研究上。光谱仪系统的数据获取的非常高度，高精度和高效率是成功搜索自由基和离子的最关键因素。为了实现这一目标，我们将俄罗斯制造的向后波振荡器作为辐射来源。使用双相锁环已经稳定了振荡频率。总结了以下主要结果，并且已经发布了有关这些结果的完整报告，将作为附录附加。与JEM/Smiles Group的合作已被衡量。这些项目也与JPL组合作进行。该项目期间获得的成就主要在以下领域：（1）不稳定物种的光谱（2）鉴定用于血浆CVD过程的排放等离子中的反应中间体。 （3原理压力扩大与地球大气化学相关的分子的测量。
