Astronomical Detection of the Interstellar Anion C<sub>10</sub>H<sup>–</sup> toward TMC-1 from the GOTHAM Large Program on the Green Bank Telescope
Astrophys. J. Lett. 944, Art. No. L45 (2023).
The identification was made by stacking data from the line survey up to 30 GHz; most signal-contribution came from the 13.1 to 19.2 GHz region. The authors also report a tentative detection of C10H with a C10H– to C10H of roughly 2. In addition, C10H– is roughly 5 times more abundant than C8H– and about one third more abundant than C6H–.
