Spectroscopy and reactivity of organic compounds in space

在射电观测中已经发现了100多种物质，然而在恒星形成区，分子的光谱学和产生机制都很复杂。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。本联合研究开展了以下研究：(1)构建用于观测碳链分子电子跃迁的脉冲喷嘴放电设备；(2)编写用于计算天体探测分子跃迁频率和谱线强度的计算机程序；(3)对CC分子进行高分辨率傅里叶变换发射研究，以获得精确的射电区跃迁频率；(4)海尔-博普彗星的射电观测；(5)利用herman - wafalls效应测定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.
