reported on the
Discovery of Interstellar 3-Cyanopropargyl Radical, CH<sub>2</sub>CCCN
Astron. Astrophys. 654, Art. No. L9 (2021).
The molecule was identified through three a-type transitions with J = 8 − 7 to 10 − 9 and Ka = 0 in the course of a molecular line survey of the prototypical cold dark molecular cloud TMC-1 carried out with the Yebes 40 m radio telescope between 31.0 and 50.4 GHz.
