导言这里所报道的工作来源于一个联合计划,其中包括:合成化学,微波光波学和射电天文学。英国Sussex大学于1975年用微波光波学方法合成并研究了聚炔H-C≡C-C≡C-C≡N。接着,在和渥太华NRC天文学家的联合射电研究计划中,采用了合成实验室微波频率,发现此化合物存在于星际空间。这一发现导致了更长的碳链分子HC_7N和HC_9N在天体星球之间的检出(图1)。最近的研究在 Introduction The work reported here derives from a joint project that includes: Synthetic Chemistry, Microwave Wavewave and Radio Astronomy. Sussex University in the United Kingdom in 1975 by microwave light wave method synthesis and study of the acetylene H-C≡C-C≡C-C≡N. Next, in a joint radio research program with NRC astronomers in Ottawa, a synthetic laboratory microwave frequency was used and found to exist in interstellar space. This finding led to the detection of longer carbon chain molecules HC_7N and HC_9N between astronauts (Figure 1). Recent research is here
