 +The authors carried out an unbiased molecular with the Yebes 40 m dish between 31 and 50 GHz toward the circumstellar envelope of the famous C-rich AGB star CW Leonis. Numerous transitions of HC<​sub>​7</​sub>​N in its lowest excited state //​v//<​sub>​15</​sub>​ = 1 were detected despite a rotational temperature of around 25 K. The derived HC<​sub>​5</​sub>​N to HC<​sub>​7</​sub>​N ratio is extremely low, roughly 2.4. The derived HC<​sub>​7</​sub>​N to HC<​sub>​9</​sub>​N ratio is still very low, roughly 7.7.\\
