| The observations were obtained in the course of the line survey Green Bank Telescope Observations of TMC-1: Hunting for Aromatic Molecules. 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. The molecules 1-cyanonaphtalene and 2-cyanonaphtalene were indentified through line-stacking with good signal-to-noise ratios. In fact, after additional observations carried out in the review process, the S/Ns of some lines of 1-cyanonaphtalene were good enough to be identified individually after modest smoothing. Apparently "poly" starts in English with 2. Both molecules are obviously not hydrobarbons, but simple hydrocarbon derivatives.\\ | The observations were obtained in the course of the line survey Green Bank Telescope Observations of TMC-1: Hunting for Aromatic Molecules.
