Spectroscopic Studies of Interstellar Matter

茨木大学天体物理学小组、斯泰西分子科学研究所光谱学小组的合作研究项目，加拿大国家研究理事会和赫茨伯格天体物理研究所射电天文学小组在1996财政年度期间进行了合作。通过双方人员的几次交流，该计划证明对双方都是非常有益的。茨木大学和国家研究理事会实验室都进行了红外和毫米波光谱学研究。到财政年度结束时，茨木亚毫米波光谱仪的研制成功，使该波段的光谱学成为可能。在红外波段，用二极管激光光谱仪和傅里叶变换光谱仪，测定了一对货车范德华络合物，CO-He和CO-Ne，结果表明，直接吸收毫米波光谱与超音速射流膨胀是足够灵敏的详细分析旋转，与国家研究理事会的两位理论家的讨论受到了热烈欢迎，并证明对双方都非常有益。

The 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 was pursued during the 1996 fiscal year.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.Toward the end of the fiscal year, Ibaraki sub-millimeter wave spectrometer was completed and the spectroscopy in that frequency region became possible.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.It was demonstrated that direct absorption millimeter-wave spectroscopy with a supersonic jet expansion was sensitive enough for detailed analysis of rotational-tunneling spectroscopy.Discussion with the two theoreticians form National Research Council was greeted with enthusiasm and proved to be very beneficial for both sides.
