This project was planned to pursue a further development of our on-going project on high-resolution spectroscopic investigation of molecular ions and free radicals which had been our main research objectives in the past several years. A major workhorse to promote our investigation is a submillimeter-wave spectrometer system. One such machine had been constructed on the basis of the past several years of research activities. The spectrometer covers the frequency range of 270-860 GHz with three back-ward wave oscillators. During the period of this research project, another similar submillimeter system has been completed. It utilizes a millimeter-wave frequency synthesizer as a local oscillator opposed to a millimeter-wave Gunn oscillator used in the old system. In addition, Fourier transform visible spectroscopy of the Swan system of C_2 and a visible system of C_3 has been carried out as a part of the collaboration with Professor Bernath at University of Waterloo by using a Bruker Fourier transform spectrometer.Major achievements obtained during this project term are mainly in the following areas.(1) Spectroscopy of molecular ions. (2) Extended investigation of the Swan band system of C_2. (3) Precise pressure broadening measurements of molecules relevant to the Earth's atmospheric chemistry.

该项目计划进一步发展我们正在进行的对分子离子和自由基的高分辨率光谱研究的项目，这是我们过去几年中我们的主要研究目标。促进我们调查的主要主力是一台毫米波光谱仪系统。一台这样的机器是根据过去几年的研究活动建造的。光谱仪涵盖了带有三个后退波振荡器的270-860 GHz的频率范围。在该研究项目期间，另一个类似的亚毫米系统已经完成。它利用毫米波频率合成器作为局部振荡器，反对旧系统中使用的毫米波Gunn振荡器。此外，通过使用Bruker傅立叶变换光谱仪，在此项目期间获得的MAJOR成就，在此项目中获得的傅立叶变换可见的C_2天鹅系统和C_3的可见系统是与Bruker Fourier Transform的合作的一部分。 （2）对C_2天鹅带系统的扩展研究。 （3）与地球大气化学相关的分子的精确压力扩大测量。
