J. Lett.// **900**, Art. No. L10 (2020).\\ 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 of the 4<sub>1,3</sub>−3<sub>1,2</sub>, 5<sub>1,5</sub>−4<sub>1,4</sub>, 5<sub>0,5</sub>−4<sub>0,4</sub>, and 5<sub>1,4</sub>−4<sub>1,3</sub> transitions near 22.6, 26.6, 27.3, and 28.2 GHz, respectively, at the expense of noise levels of about the same level as the individual lines. The analysis was improved by employing a stacking technique.\\ N. Marcelino, B. Tercero, M. Agúndez and J.
