+The data were recorded with very high resolution which resolves, at least in part, the complex velocity structure and the <sup>14</sup>N hyperfine structure splitting of the //J// = 8 → 7, 9 → 9, and 10 → 9 transitions near 22.4, 25.2, and 28.0 GHz at the expense of noise levels of about the same level as the individual lines. The analysis was improved by employing a stacking technique. The HC<sub>4</sub>NC to HC<sub>4</sub>CN ratio is about 1 to 200, while the HC<sub>2</sub>NC to HC<sub>2</sub>CN ratio is about 1 to 50.\\
