More than 100 species have been identified in radio observations, However, in star-forming region there are complexities in spectroscopy and production mechanism of molecules. The present study approaches various problems in spectroscopy and chemistry in space and higher atmosphere. The following studies have been carried out in this joint study ; (1) Construction of pulse nozzle discharge equipment for observations of the electronic transitions of carbon chain molecules, (2) Coding of computer program for calculating transition frequencies and line intensities of molecules detected in astronomical objects, (3) High-resolution Fourier transform emission study of the CC molecule for deriving accurate transition frequencies in radio region, (4) Radio observations of comet Hale-Bopp, (5) Determination of the transition dipole moment of the infrared band of CH by using Herman-Waflls effect.

在射电观测中，已经发现了100多个物种，但在恒星形成区，分子的光谱和产生机制是复杂的。本研究探讨了空间和高层大气中光谱学和化学的各种问题。在这项联合研究中进行了以下研究：（1）为观测碳链分子的电子跃迁建造脉冲喷嘴放电设备，（2）为计算在天体中探测到的分子跃迁频率和谱线强度编写计算机程序，（3）CC分子的高分辨率傅里叶变换发射研究，以获得射电区精确的跃迁频率。（4）海尔-波普彗星的射电观测，（5）利用Herman-Waflls效应测定CH的红外跃迁偶极矩。
