| The molecules were identified through a plethora of //a//-type rotational transitions, several series easier to detect because of oblate pairing of the transitions having the same //K<sub>c</sub>// close to //J//. The derived column densities were equal, and a rotational temprerature of 9 K was derived. The authours also detected many lines of 1- and 2-cyanonaphtalene, again with equal column densities. Interestingly, the column densities of these slightly smaller molecules were about a factor of 1.7 lower than those of each of the cyanoacenaphtalenes.\\ | The molecules were identified through a plethora of //a//-type rotational transitions, several series easier to detect because of oblate pairing of the transitions having the same //K<sub>c</sub>// close to //J//.
