通过 17.6 GHz 的 N = 2-1 跃迁的五个最强超精细分量，在冷星际云 TMC-1 中检测到了 C4D。发现丰度比 C{sub 4}D/C{sub 4}H = 0.0043，与化学模型一致。相比之下，TMC-1 中的 C{sub 3}HD/C{sub 3}H{sub 2} 约为 0.08，几乎比预测大一个数量级。讨论了这些不同比率对离子分子化学的影响。 21 参考文献
C4D has been detected in the cold interstellar cloud TMC-1 by means of the five strongest hyperfine components of the N = 2-1 transition at 17.6 GHz. An abundance ratio C{sub 4}D/C{sub 4}H = 0.0043 is found, in agreement with chemical models. By contrast, C{sub 3}HD/C{sub 3}H{sub 2} roughly 0.08 in TMC-1, nearly an order of magnitude larger than predicted. Implications of these discrepant ratios for ion-molecule chemistry are discussed. 21 refs.
