Detection of Interstellar //E//-1-cyano-1,3-butadiene in GOTHAM Observations of TMC-1
Astrophys. J. 948, Art. No. 133 (2023).
The identification was made by stacking data from the GBT line survey that covers ~24.9 GHZ of the 7.9 to 36.4 GHz region. The E form of 1-cyano-1,3-butadiene is less abundant than the two detected cyanocyclopentadiene isomers by factors of a few, somewhat depending on the sources of the column densities of the cyclic species.
