Spectroscopy and reactivity of organic compounds in space

射电观测已经鉴定了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。本研究探讨了在空间和更高的大气中光谱和化学的各种问题。(1)建立了观测碳链分子电子跃迁的脉冲喷嘴放电装置；(2)编制了计算天体中探测到的分子跃迁频率和谱线强度的计算机程序；(3)对CC分子进行了高分辨率傅里叶变换发射研究，以获得射电区域准确的跃迁频率；(4)对Hale-Bopp彗星的射电观测；(5)利用Herman-Waflls效应测定了CH红外波段的跃迁偶极矩。

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.
