检测IRC +10216中的C5N -和振动激发的C6H
Detection of C5N- and vibrationally excited C6H in IRC +10216
摘要：
我们报告在富C星IRC +10216的包络中检测到四个系列的谐波相关频率的线：B1389，B1390，B1394和B1401。这四个系列必须来自线性分子，其质量和大小接近C6 H和C5 N。三个系列有半整数旋转量子数，我们将它们分配给C6 H的2Delta和2Sigma振动态在其最低（V_11）弯曲模式。第四个系列，B1389，具有整数J，没有精细或超精细结构的证据;它的旋转常数为1388.860（2）MHz，离心畸变常数为33（1）Hz;它几乎可以肯定是C5 N-阴离子。
英文摘要：
We report the detection in the envelope of the C-rich star IRC +10216 of four series of lines with harmonically related frequencies: B1389, B1390, B1394 and B1401. The four series must arise from linear molecules with mass and size close to those of C6H and C5N. Three of the series have half-integer rotational quantum numbers; we assign them to the 2Delta and 2Sigma vibronic states of C6H in its lowest (v_11) bending mode. The fourth series, B1389, has integer J with no evidence of fine or hyperfine structure; it has a rotational constant of 1388.860(2) MHz and a centrifugal distortion constant of 33(1) Hz; it is almost certainly the C5N- anion.
