Spectroscopic Studies of Interstellar Matter

茨城市大学天体物理学组与斯泰西分子科学研究所光谱学组的合作研究项目。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财政年度进行了研究。事实证明，通过多次双向人员交流，该项目对双方都非常有益。红外和毫米波光谱在茨城市大学和国家研究委员会实验室进行。临近财政年度末，茨城市亚毫米波光谱仪完成，该频率区域的光谱学成为可能。在红外光谱中，利用二极管激光光谱仪和傅里叶变换光谱仪研究了CO-He和CO-Ne这两个范德华配合物。结果表明，超音速射流膨胀的直接吸收毫米波光谱具有足够的灵敏度，可用于旋转隧道光谱的详细分析。与国家研究委员会的两位理论家的讨论受到了热烈的欢迎，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.
