项目摘要

This project is closely related to the last year's collaborative research project between Astrophysics group of Ibaraki University, Spectroscopy group of Steacie institute for Molecular Sciences, National Research Council of Canada, and Radio Astronomy group of Herzberg Institute of Astrophysics. Same as the last year's project, this year we also found that the program proved to be very profitable to both sides through several exchanges of personnel in both directions. Infrared and millimeter-wave spectroscopy were conducted both at Ibaraki University and National Research Council laboratories. Ibaraki sub-millimeter wave spectrometer was brought to full operation during this fiscal year and the spectroscopy in the frequency range form 550 to 860 GHz became feasible. In the infrared, using a diode laser spectrometer and a Fourier transform spectrometer, a couple of van der Waals complexes, CO-He and CO-Ne, were studied. P. R. Bunker presented a lecture series at Ibaraki on Group Theory and Molecular Spectroscopy. It was received very favorably by graduate students as well as staff members. Feldman was involved in a millimeter-wave observation of the upper atmosphere and observed oxygen transition in the ldeltag excited electronic state. Ibaraki group determined the pressure broadening parameter of oxygen in that state which was needed in analysis of the line profile to derive altitude distribution of O2 in ldelta g state produced by photo-decomposition of ozone.

该项目与茨城大学天体物理小组、Steacie分子科学研究所光谱小组、加拿大国家研究委员会、赫兹伯格天体物理研究所射电天文学小组去年的合作研究项目密切相关。和去年的项目一样，今年我们也发现，通过几次双向的人员交流，该项目对双方都非常有利可图。红外线和毫米波光谱是在茨城大学和国家研究委员会实验室进行的。茨城亚毫米波光谱仪在本财政年度全面投入使用，在550至860 GHz的频率范围内进行光谱分析成为可能。在红外波段，用半导体激光光谱仪和傅里叶变换光谱仪研究了范德华络合物CO-He和CO-Ne。P·R·邦克在茨城举办了群论和分子光谱学系列讲座。它受到了研究生和教职员工的好评。费尔德曼参与了对高层大气的毫米波观测，并观察到了ldeltag激发电子态的氧转变。茨城小组测定了氧在该状态下的压力展宽参数，这是分析谱线轮廓所需的，以推导出臭氧光解产生的l-g态O2的高度分布。
