Astron.// **5**, 176 (2021).\\ 1-Cyanocyclopentadiene it was in this case. 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 molecule was indentified through line-stacking with quite decent signal-to-noise ratio.\\ K. L. K. Lee, P. B. Changala, R. A. Loomis, A. M. Burkhardt, C. Xue, M. A. Cordiner, S. B. Charnley, M.

J. Lett.// **910**, L2 (2021).\\ Same procedure, albeit new observations increased the signal-to-noise ratios of both molecules. Some smoothing reavealed individual lines for 1-cyanocyclopentadiene, which has stronger lines. Four lines were shown.\\ ---- Contributor(s): H. S. P.
