Spectroscopic Studies of Interstellar Matter

该项目与茨木大学天体物理学组、加拿大国家研究理事会Steacie分子科学研究所光谱学组和赫兹伯格天体物理研究所射电天文学组去年的合作研究项目密切相关。与去年的项目一样，今年我们也发现，通过多次双向人员交流，该项目对双方都非常有利。红外和毫米波光谱在茨木大学和国家研究理事会实验室进行。茨木亚毫米波分光仪在本财政年度全面投入使用，550至860 GHz频率范围内的分光变得可行。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一对货车范德华配合物：CO-He和CO-Ne。P. R.掩体提出了一系列讲座在茨木群论和分子光谱学。它受到了研究生和工作人员的好评。费尔德曼参与了对高层大气的毫米波观测，并观测到了处于ldeltag激发电子态的氧跃迁。茨木小组确定了该状态下氧气的压力增宽参数，该参数是分析谱线轮廓所需的，以推导出臭氧光分解产生的l delta g状态下O2的高度分布。

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.
