| | Eight //a//-type transitions with 5 ≤ //J// ≤ 8 and //K<sub>a</sub>// ≤ 1 were covered with complex fine and hyperfine structure splitting. Many features are close to the noise limit or blended, but sufficiently many features are clear enough and modeled well enough to view the detection as secure. A value of //T//<sub>rot</sub> = 7 ± 1 K was derived for this isomer as well. The abundance of 1-cyanopropargyl is slightly higher than that of 3-cyanopropargyl by a factor of about 1.4.\\ |
