Interstellar detection of the highly polar five-membered ring cyanocyclopentadiene
Nat. 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 14N hyperfine structure splitting. The molecule was indentified through line-stacking with quite decent signal-to-noise ratio.

reported on the
Interstellar Detection of 2-cyanocyclopentadiene, C<sub>5</sub>H<sub>5</sub>CN, a Second Five-membered Ring toward TMC-1
Astrophys. 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.
